Update docs: use `kubectl get service` instead of `kubectl get svc`
Update docs: use `kubectl get service` instead of `kubectl get svc`

- These docs seem to try to use long names for things rather than
  short names. The shortened `svc` is only referred to once on this
  page - in this example - and it was immediately jarring to me having
  just read about "services" - I asked myself "what's 'svc'?".
