[clang] [clang][NFC] order C++ standards in reverse in release pages (PR #104866)

[via cfe-commits]

https://github.com/h-vetinari created https://github.com/llvm/llvm-project/pull/104866

Noticed that the release notes currently have a weird order: C++17, C++14(!), C++20, C++23, C++2c. Reorder them in reverse chronological order, which also matches the [status page](https://clang.llvm.org/cxx_status.html).
