Automatic merge from submit-queue

restrict discoverable versions to those that have resources

Prevents versions with no resources from appearing in discovery.

@soltysh ptal.  I think you have some issues for this, mind wiring them up?

```
kubectl api-versions
apps/v1alpha1
authentication.k8s.io/v1beta1
authorization.k8s.io/v1beta1
autoscaling/v1
batch/v1
certificates.k8s.io/v1alpha1
extensions/v1beta1
policy/v1alpha1
rbac.authorization.k8s.io/v1alpha1
storage.k8s.io/v1beta1
v1
```
Fixes  #29998.
