Miscellaneous CI improvements

[twometresteve]

Goal

A few miscellaneous CI pipeline improvements:

• Allow retries on known-flaky RN CLI tests, to reduce frustration for developers while a fix is being worked on.
• Bump Android to 11 for RN tests in the hope of quicker/more stable runs.
• Increase maximum wait to receive errors to 60 seconds - the theoretical maximum for the Android notifier.
• Remove use of the resilient Appium driver. It didn't work as intended and only confused things in the case of a genuine problem.

The retry mechanism in Maze Runner is currently broken, but will be fixed shortly.

Testing

Covered by CI.
