[clang] [Clang] Simplify release notes and remove irrelevant comment (PR #96407)

[Gábor Spaits via cfe-commits]

https://github.com/spaits created https://github.com/llvm/llvm-project/pull/96407

As discussed before with @cor3ntin before (https://github.com/llvm/llvm-project/pull/94752) here is the simplification of the release note written for the previously  mentioned PR and the removal of a comment that is no longer useful.

(Sorry for creating this PR this late.)
