React Native: Remove babel deps from RN setup (not needed)

[dannyhw]

Closes #

What I did

The react native setup fails on npm for peer dependency issues related to babel, however babel and babel loader are not used at all for react native storybook so we can remove those without issue.

📝 Walkthrough

Walkthrough

The React Native Storybook generator removes the getBabelDependencies import from storybook/internal/cli and eliminates the corresponding call in configure. The packages array passed to dependencyCollector.addDependencies now contains only versionedPackages plus the optional react-dom entry. Tests are updated to remove the mock setup for this removed dependency.

Update tests to remove mock setup code/lib/create-storybook/src/generators/REACT_NATIVE/index.test.ts	Test file removes the getBabelDependencies import and the beforeEach mock that resolved it to an empty array; other mocks and assertions remain unchanged.

135-140: ⚠️ Potential issue | 🟡 Minor

Remove getBabelDependencies mock and import from test file.

The implementation correctly removes babel dependencies (unnecessary for React Native's Metro bundler), but the test file still imports and mocks getBabelDependencies at lines 3 and 38 of index.test.ts. These should be removed to keep tests consistent with the implementation changes.

Specifically, delete the import statement for getBabelDependencies from the top

getBabelDependencies (around line 38). Since the implementation no longer
collects babel dependencies for React Native, these test artifacts are no longer
needed.
