Testing

Manual testing

pnpm create expo empty-expo
cd empty-expo
pnpm create storybook

This will skep testing in storybook@latest but will install it in this updated version.

Greptile Summary

Added React Native Web (RNW) to the list of supported frameworks for test addon installation in the Storybook CLI, enabling test functionality to be included during initialization of RNW projects.

• Added ProjectType.REACT_NATIVE_WEB to supportedFrameworks array in code/lib/create-storybook/src/generators/baseGenerator.ts
• Ensures test addon is installed when initializing Storybook in RNW projects
• Fixes current behavior where testing functionality was being skipped for RNW
