fix: Use unless-stopped for docker containers to prevent unexpected starts after docker daemon reboot

[silvermind]

Description and Motivation

Has all bots restarted after a server reboot, also the one I've stopped manually.

unless-stopped is similar to always, except that when the container is stopped (manually or otherwise), it is not restarted even after Docker daemon restarts.
