Greptile Summary

Added a new 'Both' initialization option in Storybook CLI for React Native projects, enabling simultaneous setup of both native and web configurations.

• Added REACT_NATIVE_AND_RNW project type to code/core/src/cli/project_types.ts
• Implemented dual initialization logic in code/lib/create-storybook/src/initiate.ts to run both RN and RNW generators
• Improved CLI to handle installation messages for both native and web configurations separately
• Added new selection option in the CLI interface for the 'Both' configuration
• Note: Template configuration needs to be added to supportedTemplates array for complete implementation
