Use of deprecated react feature causes "TypeError: Cannot read properties of undefined (reading 'node')" when using React v15.5.0 and later

[doublethefish]

Repo:

1. In a new (instructions) or existing react-native app.
2. Ensure that you are using react 15.5.0 or later (reason)
3. Install react-native-components-viewer: npm install --save react-native-components-viewer
4. Add the react-native-components-viewer import to App.js/tsx or any component. import ComponentsViewer from 'react-native-components-viewer';
5. When the component that imports ComponentViewer is rendered the app will error with either TypeError: Cannot read properties of undefined (reading 'node') or Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication).

Root-cause:

This appears to be caused by PropTypes being moved from react to the community supported prop-types library.

Fix:

Port to the prop-type library. See PR #5
