[E2E] Invalid argument "null" for "--revision" flag: strconv.ParseInt: parsing "null": invalid syntax

Nightly job failed with Invalid argument "null" for "--revision" flag: strconv.ParseInt: parsing "null": invalid syntax
https://github.com/kubewarden/kubewarden-controller/actions/runs/9025232028/job/24800634936

I tried to run it locally, I found out that if I use latest controller image I get this error:

~ k get clusteradmissionpolicies privileged-pods -o yaml
    message: The policy webhook has not been created
    reason: PolicyActive
    status: "False"

~ k logs -n kubewarden kubewarden-controller-7b69b8b588-lfcs7

}

I am not sure if those 2 errors are related or not.

Reading the error message we can see that controller does not have the permissions to update the webhooks resources. Which makes sense, because if we take a look in the kubebuilder directive, it has permissions to patch the resources only. That's explains why we are seeing this error. Because in a recent change to use the controller-runtime helper functions we start to use CreateOrUpdate to update the resources. We should use CreateOrPatch. I'll update the code to use the later helper function.

The fix is merged in main. We will soon tag RC1 including this fix

reopening, @jvanz saw it again, but @kravciak might have fixed it in the meantime.
