Updated the versions of PHPUnit and Symfony's PHPUnit-Bridge in composer.json to more recent, stable versions. The bootstrap.php code has been modified to now load the regular .env file instead of the .env.test file, the change is made to enable the application fetch the actual environment variables during execution.
This commit involves the deletion of ChillEventBundle from the bundles configuration. Additionally, test framework configurations are handled in a consolidated manner by moving assets configurations (json_manifest_path) from test/framework.yaml to framework.yaml. The obsolete test/framework.yaml has been deleted as it is no longer needed.
