kubectl suggestion should also include aliases

[soltysh]

What would you like to be added:
This is somewhat related to #1740 issue, but this time it covers the suggestions.

I have a runx alias defined as follows:

- name: runx
  command: run
  options:
  - default: nginx
    name: image
  appendArgs:
  - --
  - custom-arg1

when trying to run, I've made a typo and tried to run kubectl runc:

$ kubectl runc
error: unknown command "runc" for "kubectl"

Did you mean this?
	run

As presented above, the suggestion ONLY considered the built-in command, would it be possible to expand the suggestions with aliases?

I would suggest, that as soon as aliases are incorporated into help, meaning available to the user through kubectl, then the suggestion should be able to refer it as well. Otherwise, it feels incomplete.

However, I'd do that as a separate issue/PR.

I could take a look at it once I'm done with help display which I think will give me a good overview on the feasibility of this task

That is one of the reasons I went with a separate issue 😉 Thank you!
