Subject: [PATCH] Improve Docker downgrade process and cleanup

Enhanced the Docker downgrade function by cleaning up old Docker repository configurations, forcing a fresh apt cache, and using --purge and autoremove to ensure a cleaner removal of Docker and its dependencies. Updated script version to 1.3.0.
