Persist test suites and set PLUGIN_DIR to GITHUB_WORKSPACE

- Update .env file creation to set PLUGIN_DIR=${GITHUB_WORKSPACE} so that plugin files (e.g. phpunit.xml) are found in the repository.
- Persist the wordpress-latest-tests-lib directory in the workspace artifact to ensure test suite configuration is available.
- Enable inclusion of hidden files in the workspace artifact upload.
- Add verification steps to check for the existence of the .env file and wp-tests-config.php before running tests.
