enable docker container versions (releases)

[limesTech]

It would be nice to introduce application releases.
This would enable readable version pinning and clean docker compose releases/updates instead of pulling :lastest containers

Can we do this by just tagging every docker image published on main with its commit hash? Or do you want actual version numbers? We could probably also have it auto-increment to something like v1.x where x is automatically increased by 1 for every commit, this seems more fragile though.

I guess commit hases are already part of your docker tags. But it would be great to distinguished between major and minor changes with v1.0 , v1.1 or v2.0 ... once in a while.
