Fix image version warning failing error_spam on every release

This check fail during every release when we test the new kicbase or iso images.

Example failure:

    error_spam_test.go:114: minikube stderr:
        ! Image was not built for the current minikube version. To resolve this you can delete and recreate your minikube cluster using the latest images. Expected minikube version: v1.39.0 -> Actual minikube version: v1.38.1

https://prow.k8s.io/view/gs/kubernetes-ci-logs/pr-logs/pull/minikube/23606/pull-minikube-docker-containerd-linux-arm/2094856253917368320

This breaks the build and require manual inspection before merging, and provide no value for users.

Can be fixed by warning only about older images. Using newer kicbase should not warn - like using --iso-url.
