[RN72] Update Babel
Summary:
As part of upgrading to React Native 0.72, react-native-upgrade-helper prompts us to update Babel.
Realized I forgot to do this as part of my stack yesterday.
Test Plan:
- I ran web, landing, and keyserver in both prod and dev and clicked around to confirm things were working
- I built and ran iOS and Android locally and confirmed things work
