Support RNW 0.18

[badsyntax]

See https://github.com/necolas/react-native-web/releases/tag/0.18.0

When attempting to use RNW 0.18 I get the following error:

Cannot find module 'react-native-web/dist/cjs/exports/StyleSheet/createStyleResolver' from 'node_modules/react-primitives/lib/injection/react-native-web.js'
