Update RN pipeline to use Maze Runner v7

Goal

Update RN pipeline to use Maze Runner v7.

Design

This was a fairly standard upgrade to v7, following the path already walked by the likes of bugsnag-android.

I did find, however, that at least one of the test scenarios (Unhandled native error) became flaky when moving to the new terminate_app/terminate_app Appium driver calls. This will need further investigation, so for now I have just stuck with the "old" close_app and launch_app calls (they seem to work absolutely fine and just output a deprecation warning). The scenario identified then passed 60/60 times for me when it was flaking at least 1/10 times.

Testing

Covered by CI.

I think this is equivalent:

Suggested change

	max_attempts = 20
	attempts = 0
	state = get_app_state
	until (attempts >= max_attempts) || state == expected_state
	attempts += 1
	state = get_app_state
	sleep 0.5
	end
	$logger.warn "App state #{state} instead of #{expected_state} after 10s" unless state == expected_state
	state
	wait = Maze::Wait.new(interval: 0.5, timeout: 10)
	state = get_app_state
	success = wait.until do
	state = get_app_state
	state == expected_state
	end
	$logger.warn "App state #{state} instead of #{expected_state} after 10s" unless success
	state

Thanks - I shall try to remember to update this the next time I'm there, rather than suffer a full rebuild on CI right now.
