I've fixed the borked :latest tags like this:

skopeo --insecure-policy copy --all docker://quay.io/rhdh/rhdh-hub-rhel9:{1.2,latest}
skopeo --insecure-policy copy --all docker://quay.io/rhdh/rhdh-rhel9-operator:{1.2,latest} 
skopeo --insecure-policy copy --all docker://quay.io/rhdh/rhdh-operator-bundle:{1.2,latest}
