test: use react-native-test-app for example, updated example

- no longer using detox, all the tests were manual anyway
- react-native 0.82.1 is current version, used here
- new types for react-native meant some module typings changed
- ios-config.sh needs one more lookup iteration for react-native-test-app
  (but I searched for the specific sub-dir rather than change general lookup count, backwards-compatible)
