Subject: [PATCH] Deprecate MapView in favor of airbnb/react-native-maps

Summary:
Compared to the `<MapView>` that comes with React Native, [react-native-maps](https://github.com/airbnb/react-native-maps) work on Android and is more feature complete. It is actively maintained and used extensively (9.2k installs / month, see [JS.Coach](https://js.coach/react-native/react-native-maps?search=react-native-maps)).

We think now is a good time to switch to react-native-maps in your applications and make `react-native-maps` the official `<MapView>` implementation for React Native.

We are going to release the deprecated `<MapView>` as a separate npm module so you can migrate to `react-native-maps` at your own pace.

**Test Plan**

Checked the docs render correctly on the website:

```
cd website
npm install
npm start
```
