Merge pull request #37636 from juanvallejo/jvallejo/bugfix/print-resource-kind-when-single-resource-type

Automatic merge from submit-queue

add resource prefix to multiple items w/ same kind

**Release note**:
```release-note
release-note-none
```

This patch ensures that a resource prefix is added to multiple items of
the same kind, when using `kubectl get all`. Before, a prefix was added only
when a single item was returned on `kubectl get all`, but ignored if only a
single resource kind existed but multiple items for that kind were
returned.

**Example**
```
$ kubectl get all
No resources found.

$ kubectl create service loadbalancer testsvc1 --tcp=8080
$ kubectl get all
NAME               CLUSTER-IP       EXTERNAL-IP                     PORT(S)    AGE
svc/testsvc1       172.30.119.220   172.46.100.155,172.46.100.155   8080/TCP   1h

$ kubectl create service loadbalancer testsvc2 --tcp=8081
$ kubectl get all
NAME               CLUSTER-IP       EXTERNAL-IP                     PORT(S)    AGE
svc/testsvc1       172.30.119.220   172.46.100.155,172.46.100.155   8080/TCP   1h
svc/testsvc2       172.30.241.197   172.46.164.158,172.46.164.158   8081/TCP   1h
```
