Fixed Safari footnotes in release notes

"arguments" isn't a legal argument name in strict mode JS. The JS
runtimes that Jasmine runs in allow it, but jsdoc doesn't.

+        Thanks for taking the time to report a bug. Please follow these steps first.
+
+        ## Troubleshooting
+        Please take the time to rule out issues with your code or third party libraries before filing a bug report. If you are reporting an error, try to determine whether the error is coming from Jasmine, another library, or your own code.
+
+        Check the [FAQ](https://jasmine.github.io/pages/faq.html) and any other relevant [documentation](https://jasmine.github.io/pages/docs_home.html) to see if your issue has already been addressed.
+
+        ## Special troubleshooting steps for asynchronous scenarios
+        If the issue has to do with testing asynchronous code, please read the [async tutorial](https://jasmine.github.io/tutorials/async) and the async section of the FAQ. In particular, check for the following common errors:
+
+        * Are you trying to write a synchronous test for asynchronous code?
+        * Does the test signal completion before the code under test finishes?
+        * Do expectations run before the code that they're trying to verify?
+
+        ## Try the latest version of Jasmine
+        If at all possible, upgrade to the latest versions of `jasmine-core` and any other relevant packages (e.g. `jasmine`, `jasmine-browser-runner`). If you can't do that, please check the [release notes](https://github.com/jasmine/jasmine/tree/main/release_notes) for all newer versions to make sure that the bug hasn't already been fixed.
+
+        ## Put together a [minimal, reproducible example](https://stackoverflow.com/help/minimal-reproducible-example)
+        Please help us help you by creating a minimal but complete setup that demonstrates the problem. Remove any code and libraries that aren't absolutely necessary, but make sure it doesn't depend on any code you haven't included. In many cases a simple code snippet is enough. In cases involving external libraries, *especially* Karma or Angular, we're likely to need a runable Git repository or jsbin/stackblitz/etc.

 For evergreen browsers, each version of Jasmine is tested against the version of the browser that is available to us
 at the time of release. Other browsers, as well as older & newer versions of some supported browsers, are likely to work.
 However, Jasmine isn't tested against them and they aren't actively supported. 
 
+\* Supported on a best-effort basis. Support for these versions may be dropped
+if it becomes impractical, and bugs affecting only these versions may not be
+treated as release blockers.

+# Jasmine 4.4.0 Release Notes
+
+## Changes
+
+* Optimized the process of transitioning between specs in Node, Safari, and
+  Edge. This change reduces the run time of jasmine-core's own test suite by
+  50-70% in Node, about 20% in Edge, and 75-90% in Safari. Your results may
+  vary. In general, suites with many fast specs will see the greatest
+  performance improvement.
+
+* Removed old code to support browsers that don't provide 
+  addEventListener/removeEventListener.
+
+## Supported environments
+
+jasmine-core 4.4.0 has been tested in the following environments.
+
+| Environment       | Supported versions |
+|-------------------|--------------------|
+| Node              | 12.17+, 14, 16, 18 |

+# Jasmine Core 4.6.1 Release Notes
+
+## Summary
+
+This is a one-time backport of bug fixes from 5.x, for the benefit of Karma
+users who may not be aware that they're still using 4.x.
+
+No further 4.x releases are planned. If possible, you should upgrade to the
+latest 5.x instead of 4.6.1. If you're using Karma, you can do this by 
+installing jasmine-core 5.x and adding an override to package.json:
+
+```
+{
+    // ...
+    "overrides": {
+        "karma-jasmine": {
+            "jasmine-core": "^5.0.0"
+        }
+    }
+}
+```
+
+## Bug Fixes
+
+* Removed unnecessary throw when building stack trace
+
+* Fixed error when formatting Error object with non-Error cause property
+
+  Merges [#2013](https://github.com/jasmine/jasmine/pull/2013) from @angrycat9000.
+
+  Fixes [#2011](https://github.com/jasmine/jasmine/issues/2011).
+
+* Accessibility: Always provide a non-color indication that a spec is pending
+
+* Accessibility: Improved contrast of version number and inactive tab links
+
+## Supported environments
+
+jasmine-core 4.6.1 has been tested in the following environments.
+
+| Environment       | Supported versions |
+|-------------------|--------------------|
+| Node              | 12.17+, 14, 16, 18 |

+# Jasmine Core 5.0.0-alpha.0 Release Notes
+
+## Summary
+
+This release primarily adds support for parallel execution via the `jasmine`
+package. Please see its release notes and the 
+[parallel documentation](https://jasmine.github.io/tutorials/running_specs_in_parallel)
+for more information. Additionally, this release cleans up a few outdated
+interfaces.
+
+This is a pre-release for a major version. It contains breaking changes, and
+there may be further breaking changes between this release and the final 5.0.0
+release.
+
+## Breaking changes
+
+* Use addEventListener in browsers rather than setting window.onerror
+
+  This simplifies error handling in browsers, makes Jasmine's own integration
+  tests easier to debug, and provides stack traces for more unhandled
+  exceptions. However, some browsers will provide less error information when
+  the error comes from a file:// URL. Additionally, Jasmine will no longer
+  override existing onerror handlers, and setting window.onerror will no longer
+  override Jasmine's global error handling. (Use `jasmine.spyOnGlobalErrors`
+  instead.)
+
+* Made Env#execute async
+* Env#execute no longer takes a callback
+* The `boot` function exported by the core module returns the same object
+  every time it's called.
+* Removed node_boot.js. Use the exported `boot` function instead.
+
+### Changes to supported environments
+
+The following previously supported environments are no longer supported:
+
+* Node <16.14
+* Safari 14
+* Firefox 91
+
+Although this release may still work in some of those environments, we no
+longer test against them and won't try to maintain compatibility with them in
+future releases.
+
+## New features
+
+* Support for parallel execution in Node.js using the `jasmine` package
+
+## Bug fixes
+
+* The global error handler is uninstalled at the end of env execution.
+
+## Supported environments
+
+jasmine-core 5.0.0-alpha.0 has been tested in the following environments.
+
+| Environment       | Supported versions |
+|-------------------|--------------------|
+| Node              | 16.14+,         18 |
+| Safari            | 15-16              |
+| Chrome            | 111                |

+* Fixed error when formatting Error object with non-Error cause property

+  Fixes [#2011](https://github.com/jasmine/jasmine/issues/2011).
+  
+* Added `throwUnless` and `throwUnlessAsync`
+
+  These are similar to `expect` and `expectAsync` except that they throw
+  exceptions rather than recording matcher failures as spec/suite failures.
+  They're intended to support using Jasmine matchers in [testing-library's](https://testing-library.com/)
+  `waitFor`, and also provide a way to integration-test custom matchers.

+# Jasmine Core 5.4.0 Release Notes
+
+## Changes
+
+* Fixed de-duplication of exception messages containing blank lines on Node and Chrome
+
+  This is particularly helpful when reporting testing-library errors, which
+  have messages that contain blank lines and can be hundreds or even thousands
+  of lines long.
+
+* Document that the expected and actual properties of expectation results are deprecated
+
+  The values of these properties are not reliable in configurations where 
+  reporter messages are JSON serialized. They appear to have been seldom if ever 
+  used. They will be removed in the next major release. 
+
+* Added Firefox 128 (current ESR) to supported browsers
+
+## Supported environments
+
+This version has been tested in the following environments.
+
+| Environment       | Supported versions      |
+|-------------------|-------------------------|
+| Node              | 18, 20, 22              |

+| Edge              | 129*                    |
+
+\* Evergreen browser. Each version of Jasmine is tested against the latest
+version available at release time.<br>
+\** Environments that are past end of life are supported on a best-effort basis.
+They may be dropped in a future minor release of Jasmine if continued support
+becomes impractical.

+# Jasmine Core 5.5.0 Release Notes
+
+## Changes
+
+* Optionally enforce uniqueness of spec and suite names
+
+  This is off by default for backwards compatibility but can be enabled
+  by setting the `forbidDuplicateNames` env config property to true.
+  Fixes [#1633](https://github.com/jasmine/jasmine/issues/1633).
+
+* Include property value mismatches in diffs even when there are missing or

+# Jasmine Core 5.6.0 Release Notes
+
+## Changes
+
+* Added [toHaveNoOtherSpyInteractions](https://jasmine.github.io/api/5.6/matchers.html#toHaveNoOtherSpyInteractions) matcher
+  * Merges [#2051](https://github.com/jasmine/jasmine/pull/2051) from @Eradev

+  * Merges [#2045](https://github.com/jasmine/jasmine/pull/2045) from @MattMcCherry
+
+* Improved error messages when non-promises are passed to built-in async matchers
+  * Merges [#2049](https://github.com/jasmine/jasmine/pull/2049) from @andiz2
+  * Fixes [#2037](https://github.com/jasmine/jasmine/issues/2037)
+
+* Added [toHaveClasses](https://jasmine.github.io/api/5.6/matchers.html#toHaveClasses) matcher
+  * Merges [#2046](https://github.com/jasmine/jasmine/pull/2046) from @aYorky 
+
+## Documentation updates
+
+* Demoted Safari to best-effort support
+  
+  Due to limited availability of Safari versions for contributors and maintainers
+  as well as in CI, Safari will be supported on the same best-effort basis as
+  environments that are past end of life, such as previous Firefox ESR versions. 
+  See [this discussion](https://github.com/jasmine/jasmine/discussions/2050) for
+  more information about why this change was made and what to expect.
