Sorry for the noise.

Two issues led to this error:

1. @react-native-webapis/web-storage was missing react-native-windows under peerDependencies
2. @react-native-community/cli config doesn't read peerDependencies, but does read devDependencies
   • config ignores peerDependencies and instead reads devDependencies react-native-community/cli#2419
