Enhance GitHub Actions workflow for improved testing visibility

- Added 'tree' command to display the directory structure at various stages of the testing process, providing better insight into the file organization.
- Included debug output for the PHPUnit execution to facilitate troubleshooting.
- Ensured that the phpunit.xml file is correctly located before running tests, enhancing the reliability of the testing framework.

These changes improve the clarity and maintainability of the testing workflow, aiding developers in understanding the project structure during test execution.
