ART components should be imported from @react-native-community/art

[WaldoJeffers]

As part of the Lean Core effort, ART will not be exported from react-native anymore.

import { ART } from 'react-native' // won't work

Instead, ART components should be imported from @react-native-community/art.

import { Shape } from '@react-native-community/art'

This is already causing issues when using this library with react-native-web, which has already removed ART from its exported modules (though I'm unsure why the authors did not wait to be in sync with React Native 🤔 ).
