Register the ClusterInformation write-protection webhook in the ValidatingWebhookConfiguration. This routes Create/Update/Delete requests for clusterinformations to the /cluster-info handler on the webhook server, which blocks writes from non-system users. The handler itself is implemented in projectcalico/calico#12010. Ref: CORE-12369
