fix: Add /federate nonResourceURLs permission to Prometheus ClusterRole

[anispate]

Adds the /federate endpoint permission to the auto-generated Prometheus ClusterRole to fix HTTP 403 Forbidden errors when ServiceMonitors attempt to scrape metrics from the /federate endpoint.

This resolves the issue where CMO federation to hypershift-monitoring-stack fails on all MC clusters because the ClusterRole was missing the required nonResourceURLs permission.
