Merge pull request #32230 from juanvallejo/jvallejo_update-kubectl-expose-output-to-usage-error

Automatic merge from submit-queue update `kubectl expose` output to UsageError **Release note**: ```release-note NONE ``` This patch updates `kubectl expose` output (with no resources provided) to a UsageError so that the `kubectl expose -h` suggestion is displayed. ##### Before `$ kubectl expose` ``` error: You must provide one or more resources by argument or filename. Example resource specifications include: '-f rsrc.yaml' '--filename=rsrc.json' 'pods my-pod' 'services' ``` ##### After ``` error: You must provide one or more resources by argument or filename. Example resource specifications include: '-f rsrc.yaml' '--filename=rsrc.json' 'pods my-pod' 'services' See 'kubectl expose -h' for help and examples. ```
