(fix) Add ClusterExtensionRevision permissions to upgrade test RBAC

The upgrade test ServiceAccount needs permissions to manage
ClusterExtensionRevisions when BoxcutterRuntime is enabled.
Without these permissions, the upgraded controller cannot create
or update ClusterExtensionRevision resources, causing the
ClusterExtension to fail reconciliation after upgrade.
