Refactor GitHub Actions workflow to improve PHPUnit configuration and…

… debugging

- Updated the workflow to create a phpunit.xml file dynamically instead of copying it from the .github/drupal directory, ensuring the correct configuration is always used.
- Enhanced debug output by displaying workspace paths and current directory contents, aiding in troubleshooting.
- Improved visibility of the directory structure before and after copying project files, facilitating better understanding of the testing environment.

These changes enhance the reliability and clarity of the testing framework, streamlining the testing process for developers.
