Use dynamic PHP matrix from composer via php-version-action

[Codex]

CI should derive PHP test versions from composer.json instead of hardcoding them.

• PHP version discovery: Add php-versions job using antfroger/php-version-action@v1 to read the supported PHP range.
• Dynamic test matrix: Feed the action’s matrix output into the tests job, replacing the fixed list of PHP versions.

jobs:
  php-versions:
    uses: antfroger/php-version-action@v1
    id: php-versions
    outputs:
      matrix: ${{ steps.php-versions.outputs.matrix }}

  tests:
    needs: php-versions
    strategy:
      matrix:
        php: ${{ fromJson(needs.php-versions.outputs.matrix) }}

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
