Document that disabling enable-cadvisor-json-endpoints flag does not disable stats summary endpoint

Update the help text for kubelet's enable-cadvisor-json-endpoints flag to explicitly mention that it has no effect over the /stats/summary endpoint.

This matches https://github.com/kubernetes/kubernetes/blob/master/cmd/kubelet/app/options/options.go#L372
created to fix kubernetes/kubernetes#96483 .
