Build APKs

1. Change scenario import in FabricEnabled/index.js

• At the moment, if using navigation scenario, you also need to git checkout navigation

2. Copy code to FabricDisabled

# Copy code
cp -R FabricEnabled/index.js FabricDisabled
cp -R FabricEnabled/scenarios FabricDisabled

3. Make release builds

# Run builds
cd FabricEnabled/android && ./gradlew assembleRelease
cd FabricDisabled/android && ./gradlew assembleRelease
