Summary:
This diff adds required Detox integrations to the RNTester app to be able to run Detox end-to-end tests on the Android version of the app.
* Instructions at https://github.com/wix/Detox/blob/master/docs/Introduction.Android.md were followed.
* The `minSdkVersion` version for the app was bumped to 18, as required by Detox.
* I also added build and test configurations in `package.json`
* The debug app is able to run some of the existing tests, but the release app instacrashes. I do not know the reason for the instacrash at this time.
* CI integrations to build and test the Android app will be added in future diffs
