fix: Add OCI labels to image (#23578)

this adds Docker Labels according to the OCI Image Format Specification
which means that tools like renovate can automatically find the
changelogs from a docker image, helping the people like me judge the
impact of upgrading their z2m instance from the pull request renovate
generates.
