[Federation] Kubefed doc fix

Fixes https://github.com/kubernetes/kubernetes/issues/50615
@kubernetes/sig-federation-bugs 
@madhusudancs, would it be of any reason to have separate code for kubefed for the version and options subcommands (rather then using ```kubectl.NewCmdVersion()``` and ```kubectl.NewCmdOptions```). I dont see the need, but I might be missing something.
