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.

-        Jasmine is supported by volunteers working in their free time. Although we're generally willing to help, we're going to ask you to put in some effort first to help us help you.
-
-        ## Troubleshooting
-        Please take the time to rule out problems with your code or third party libraries before opening an issue. If you're running into 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 question has already been answered. Consider searching [Stack Overflow](https://stackoverflow.com/questions/tagged/jasmine) and past issues in this repository for related questions as well.
-
-        ## 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?
-
-        ## Consider asking Angular questions in an Angular forum
-
-        Questions like "how do I test this Angular service" are mostly about Angular, not Jasmine. You'll likely get better responses in an Angular forum. Here's a rule of thumb: If you can't demonstrate the problem without Angular, you probably have an Angular question.
-
-        ## 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`).
-
-        ## 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.

+# 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 
+  extra properties
+
+## Supported environments
+
+This version has been tested in the following environments.
+
+| Environment       | Supported versions      |
+|-------------------|-------------------------|
+| Node              | 18, 20, 22              |
+| Safari            | 15-17                   |
+| Chrome            | 131*                    |
+| Firefox           | 102**, 115**, 128, 132* |
+| Edge              | 131*                    |
+
+\* 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 5.6.0 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
+  * Fixes [#1991](https://github.com/jasmine/jasmine/issues/1991)
+
+* Added [toBeNullish](https://jasmine.github.io/api/5.6/matchers.html#toBeNullish) matcher
+  * 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.
+
+
+## Supported environments
+
+This version has been tested in the following environments.
+
+| Environment       | Supported versions      |
+|-------------------|-------------------------|
+| Node              | 18, 20, 22              |
+| Safari            | 15**, 16**, 17**        |

+| Firefox           | 102**, 115**, 128, 135* |
+| Edge              | 132*                    |
+
+\* Evergreen browser. Each version of Jasmine is tested against the latest
+version available at release time.<br>
+\** 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.
