We are currently using an intermediate registry to pull the prow images: https://github.com/kubevirt/project-infra/blob/2aa7c952a9ae348c2c4b51e87c803b8a45c0730f/github/ci/prow-deploy/kustom/base/manifests/test_infra/current/deck_deployment.yaml#L41

Work to push towards registry.k8s.io is still ongoing: https://kubernetes.slack.com/archives/CDECRSC5U/p1727774117129299

At some point push target is expected to change here: https://github.com/kubernetes-sigs/prow/blob/8442fff47c208254cf206fca5dbfbf6191828c91/cloudbuild.yaml#L13

We then need to adapt the hack/bump-prow.sh and the image references after the publishing of images for prow has moved to registry.k8s.io
