Subject: [PATCH] RN: Set `react.runtime=automatic` in Flow Config (#50001)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/50001

Updates `react-native/.flowconfig` with the following option:

```
react.runtime=automatic
```

This adjusts Flow to model the current behavior of React and JSX, relaxing the requirement that JSX elements have `React` within scope.

Changelog:
[General][Changed] - Changed Flow for the React Native monorepo, so that `React` no longer has to be in scope when using JSX.
