sync-images: sync all images including their different aarch

The sync is not syncing the different architectures supported by the
images atleast for grafana. And hence only the amd64 gets mirrored to
the quay repo and causes issues to arm64 builds. I saw that skopeo
supports an `--all` opton that copies every aarch.
