feat: make the vanilla example app the first option (#654)

### Summary

This makes the vanilla example app the first option when the CLI asks
for the type of the example app.

We were seeing some RNTA specific bugs such as #639

With that being said, this is in no way an attempt to fix the bugs that
are caused by create-react-native-library when we integrate with the
React Native Testing App. Such bugs should still be fixed by the team.

### Test plan

1. Run creact-react-native-library
2. Pick a native library template
3. Make sure when the example type is asked, vanilla example is the
first option.
