Add source urls to docker so tools can find sourcecode

[halkeye]

For tools like renovate or dependabot, they like to put changelog notes in PRs updating deps. Having the labels allows the tools to link it back to sourcecode and share commits/release notes

If you want, I can update your github actions to use docker/metadata-action like i did for https://github.com/plankanban/planka/pull/680/files

What kind of labels does this add in addition?
