Change supervisor_update_pending text

During onboarding, Supervisor may be out of date relative to the core
version being installed. Attempt a Supervisor update at the start of
async_setup_entry when not yet onboarded:

- SupervisorBadRequestError: no update available, proceed normally.
- No exception: update was triggered, raise ConfigEntryNotReady to
  retry once Supervisor has restarted with the new version.
- Any other SupervisorError: unexpected failure communicating with
  Supervisor, raise ConfigEntryNotReady to retry.
