Automatic updates via dependabot or renovate

[compscidr]

The build process of new container images is dependant on the build and deploy GH actions workflows.

I have dependabot and renovate configured, however, they aren't really able to catch the way this is configured (I use a build matrix and am currently manually making a PR to append the latest build tag from https://github.com/Lolliedieb/lolMiner-releases/releases)

It looks like there are some requests from renovate: renovatebot/renovate#24817 to support this type of usecase, but its not straightforward yet (although one of the requesters of the feature seems to have proposed a possible solution).

This needs some time and attention but ultimately could make updates almost automatic.

Need to still make it make releases after dependabot merges
