For kubernetes projects, if we want to use the sig.k8s.io group for CRDs, we need to provide the annotation api-approved.kubernetes.io. Otherwise, apiserver rejects the CRD.

As a result, we have to manually edit the CRDs produced by controller-gen and continuously edit the files every time there is a type update.

Using kustomize is not possible, because the env-test doesn't load them and it could be problematic to do so (it's an additional dependency).
