Add PhpCsFixer workflow for linting on PRs and pushes

This commit introduces a new GitHub Actions workflow to automatically run PhpCsFixer lint checks on every push and pull request. It supports PHP versions 8.2 and 8.3, and installs the highest dependency versions. The workflow provides feedback on the linting process, indicating success or failure with custom messages.
