Merge pull request #50247 from tcharding/kubectl-explain 

Automatic merge from submit-queue (batch tested with PRs 50257, 50247, 50665, 50554, 51077)

Add whitespace to improve error msg clarity

**What this PR does / why we need it**:

Currently when `kubectl explain` is called without a resource the error message is tacked onto the end of the list of valid resources. The error is clearer if there is a new line after the valid resource list, this also causes the error to be left aligned instead of indented level with the valid resource list.

```release-note
