Automatically restart GitHub runner when no job is running but the container can be restarted

The goal of this feature would be to update when an update can be performed by pulling from the repo during downtime. This would be like a pseudo auto upgrade, not using the official, unverifiable auto update system.

This can also be achieved if the runner automatically restarts when it needs to but a new version can't be achieved. This happens at some point, triggering a script called safe_sleep.sh but I am unsure of what component I can use to hook into it.
