CRA webpack config alias for "react-native-web" not respected

[jayshah123]

Describe the bug

Default CRA webpack config contains an alias for react-native as react-native-web.
When adding storybook via npx sb init, running storybook with react-native stories fails because it is not finding the alias given by CRA.

Steps to reproduce the behavior

1. npx create-react-app storybook-web-app
2. cd storybook-web-app && npx sb init
3. yarn storybook --debug-webpack
4. Unable to see alias for "react-native" as "react-native-web" which is present in default CRA.

Expected behavior

Aliases from CRA should be present.
