Migrate off Kubernetes Prow

[samuelkarp]

Per kubernetes/k8s.io#7709, we are being asked to migrate containerd's Kubernetes-related CI (sig-node e2e tests) off the Kubernetes project Prow. It has been suggested that we can run the same e2e tests in GitHub Actions, but this is TBD.

As far as I'm aware, the request is to migrate off by the end of 2025.

@samuelkarp is the bot going away too?

[samuelkarp]

Yes, I believe so. We'll have to look for alternatives for any functionality we want to keep. I found https://github.com/googleapis/repo-automation-bots this morning; some of these look like they might be viable replacements.
