Special notes for your reviewer:

If you are promoting an image, please make sure you have done the following:

• I have verified the digest with gcrane and added it as a comment to the PR or in the body.

• I'm promoting a multi-arch image that matches all the supported platforms of Kubernetes.

• I'm not promoting a tag that resolves to latest or moving tags as these are not supported

• registry.k8s.io is an immutable registry and I'll need to cut a new release if the digest is wrong.
