Subject: [PATCH] Support commands as strings in ViewPagerAndroid

Summary:
See https://github.com/facebook/react-native/commit/3cae6fa950eed54bccccf61a28c0e85d5a004c6c for more context

This component isn't exposed from the public API anymore because it has been moved to https://github.com/react-native-community/react-native-viewpager

This change will need to be made there but for FB internal which is still using this native code for now we need this migration
