[stable/metrics-server] Add release.Namespace in meta (#21832)

Adding release.Namespace in meta fixes issues
when rendering template with 'helm template --namespace'.
Without it, the rendered templates do not have the
namespace defined which is problematic when using
a gitops approach. This is also a requirement for
a tool like Spinnaker.
