What would you like to be cleaned:

Stop using the gcr.io images as https://github.com/kubernetes-sigs/kueue/blob/main/test/util/e2e.go#L28-L33.

Why is this needed:

The gcr.io image registry is deprecated and will be shut down in 2025: "After March 18, 2025, Container Registry will be shut down.", see: https://cloud.google.com/artifact-registry/docs/transition/transition-from-gcr.
