[skip ci] Sync CODEOWNERS (#15017)

This repeats the sync as noted in the GH-13591 and the discussion
https://news-web.php.net/php.internals/124472

The CODEOWNERS file is related to the targeted branch in the pull
request and not only the master branch.

- Added a note to change the earliest supported PHP branch and not only
  master branch
- Synced GitHub ID's and paths across the PHP-8.2, PHP-8.3 and master
  branches
- Add note how changes here should be analogous to bug fixes
  with a link to CONTRIBUTING.md which describes which branch to
  target
