The 0.1.48 release process was snagged by an error seen in the `poll-upstream-sources` job. The error related to the base image tag for the openshift-compliance-operator container.
In order to move past this error, the follow tag was removed:
https://code.engineering.redhat.com/gerrit/c/openshift-compliance/+/307775/1/distgit/containers/openshift-compliance-operator/Dockerfile.in
We should investigate what is required for following the golang builder update properly. (it might not be supported by the usrc updater)
