switch GCR -> Artifact-Registry

GCR has been deprecated [0] in favour of Artifact-Registry.

Thus, change push-targets for OCI-Images:

- europe-docker.pkg.dev/gardener-project/snapshots for snapshots
- europe-docker.pkg.dev/gardener-project/releases for releases
- europe-docker.pkg.dev/gardener-project/public for read-access to
  snapshots + releases
