Get rid of kubernetes-release/archive

[saschagrunert]

The archives are inherited from anago times, for example: https://console.cloud.google.com/storage/browser/kubernetes-release/archive/anago-v1.31.0

They mainly contain:

• the build logs (available using GCB)
• the announcement (can be moved over to kubernetes-release/release/v1.31.0)
• the release notes html and JSON (not used, because already part of kubernetes-release/release/v1.31.0)
• the archive k8s.io.tar.gz (probably not needed)

The idea is to move the announcement into the release artifacts (release/v1.y.z) directory and completely avoid collecting the archive. All of that can be done in krel.

We should drop the archive k8s.io.tar.gz and the release logs to begin with.

Starting to work on this in #3717

the build logs (available using GCB)

I do think this should probably be published publicly? We have a build process that is not fully reproducible.

Funnily we just publish the release logs right now, but not the stage ones. I think we have to follow-up on that. I'm not sure what the best way is to deal with them.
