PHP 8.4 release notes
PHP 8.4 has been released 2.5 weeks ago, but there is no dev container image yet that supports this version.
I would like to start developing and testing our codebase with this version.

• Open a PR
• Create a release
• Update templates (if necessary)
• Update [Tracking] Image support, deprecation / EOL dates #90
• Update Microsoft Artifact Registry docs

Thanks for opening! If you'd like to open the PR to add this support, we'd welcome the contribution (please feel free to tag me if so)!
