currently this image is built from this code
https://github.com/spowelljr/kube-registry-proxy and it is used by Registry addon
this image used to be maintained by upstream kubernetes but they abandoned it, so minikube continued publishing it for Registry addon (example #20838)

it is currently hosted in internal minikube gcp project but since older images of kube-registry-proxy gets CVEs they will be removed from internal google gcp projects.

we will need to publish this image somewhere else, either publish it in github container registry or preferably in K8s-infra
