Switch Picker from react-native to @react-native-community/picker

[nweintraut]

Hi. The picker component in react-native is being moved to @react-native-community/picker (See https://reactnative.dev/docs/picker) Right now, it generates the following warning: ExceptionsManager.js:173 Warning: Picker has been extracted from react-native core and will be removed in a future release. It can now be installed and imported from '@react-native-community/picker' instead of 'react-native'. See https://github.com/react-native-community/react-native-picker

Thanks, Neil

Well, apparently this repo is abandoned and Picker was removed in v0.66.0, so now it's crashing the app. But I'm guessing at this point, everyone has already forked it 😅
