This reverts commit d24f648db8.
This is a partial revert that only moves the image publication location
to quay. A followup change will update the image consumption location.
We split them up to avoid problems if image promotion does not succeed.
We're able to make this change because both the zuul and gitea load
balancers as well as teh zookeeper cluster are running on Noble with
podman now. This means we don't lose speculative testing of container
image updates when the images are hosted on quay.
