Update to Detox 9 (#21570)

Summary:
Updating to Detox 9 - this should help with better Xcode 10 support, and should fix https://github.com/facebook/react-native/issues/21539.

I've updated to fixed `9.0.4` since it seems that each version is fairly different from the next, and I've followed the [migration guide](https://github.com/wix/detox/blob/master/docs/Guide.Migration.md#migrating-from-detox-8xx-to-9xx) for the android native dependencies.

Release Notes:

[INTERNAL] [ENHANCEMENT] [DETOX] - Update to version 9.0.4
