Description

• fix config.php addtitional field by moving it to before the require_once line. it has no effect otherwise
• split pgp.ini and config.php into a configmap and a secret respectively to allow for:
• allow replacing the config.php with one from an existing Secret
• create new secret for moodle-database values (except password), that is used by backup/restore. so that backup/restore can work properly with all possible databases

tested backup restore successfully 🥳
