Docker Hub image for GitLab Runner 15.0.0 has only amd64, not arm64 or ppc64le
The GitLab Runner container image on hub.docker.com normally supports three architectures: linux/amd64, linux/arm64 and linux/ppc64le.
The tags for v15.0.0, e.g., alpine-v15.0.0
support only amd64.
There's nothing that I can see in the GitLab 15.0 release notes to suggest the other architectures are being dropped intentionally.
