	yq -i e '(select (.helm.values.image) | .helm.values.image.repository) |= "docker.io/library/networking-calico-local"' $repo_root/tmp/controller-registration.yaml
	kubectl apply --server-side --force-conflicts -f "$repo_root/tmp/controller-registration.yaml"

to be changed to something like https://github.com/gardener/gardener-extension-registry-cache/blob/c924400d255feba1266d5f943a2e64ec625ff210/hack/ci-e2e-kind.sh#L36-L40.

make docker-images pulls the golang image from docker.io defined in the Dockerfile. With skaffold this is likely avoided.

Why is this needed:
To prevent dockerhub rate limit issues for e2e executions in prow.
