Summary:
- Companion PR to https://github.com/facebook/metro/pull/1085
- The Fast Refresh changes appear to be required for using static rendering and React DOM. In frameworks like Expo Router which support both native and web, this causes users to not be able to use Fast Refresh on web.
## Changelog:
[GENERAL] [CHANGED] - Upgrade React Refresh package from 0.4.0 to 0.14.0
Pull Request resolved: https://github.com/facebook/react-native/pull/39486
Test Plan:
1. In a React Native project's `package.json`:
```json
"resolutions": {
"react-refresh": "~0.14.0"
},
```
2. Start the server with a clear Metro cache.
3. Changes should update while preserving React state.

Source is not required for `getPreset` of `react-native/babel-preset`. There is a codition that adds `react-native/babel-plugin-codegen` to the preset only if source is passing certain regex. This condition fails if source is null, but that's wrong because the plugin may still be requred for this transformation even though source is not provided.
This diff changes the condition so the regexp tests source only if it is not null, and `react-native/babel-plugin-codegen` automatically added to the preset otherwise.
