Fix RN bundle phase: align metro-config and babel-preset with RN 0.85

The "Bundle React Native code and images" Xcode build phase failed
because @react-native/metro-config and @react-native/babel-preset were
pinned to 0.79.x while react-native is 0.85.3. The 0.79 metro-config
API is incompatible with the 0.85 bundler script.

Also fixes xcodebuild_formatter from "" to "cat" to avoid empty pipe.
