Update React Native to New Architecture (v0.76)

[birkskyum]

Motivation

We're currently at "react-native": "^0.74.6"

The new New Architecture is default from 0.76. In this new version async bridge is removed entirely.

This makes for better performance (lower overhead c++ <-> js), and allow sync+async, where prior is async only, which allow for some flattening of callbacks to sync code etc.

In addition the debugging experience is built around Chrome DevTools.
