Restore paperComponentName: 'RCTSwitch' to fix @testing-library/react-native queries (#58323)

Summary:
Pull Request resolved: #58323

Restore `paperComponentName: 'RCTSwitch'` in `SwitchNativeComponent.js` and regenerate affected snapshots to fix test breakages introduced by D117877024.

`testing-library/react-native` 13.3.3 hardcodes `HOST_SWITCH_NAMES = ['RCTSwitch']`, so renaming the component to `Switch` broke `getByRole('switch')` queries and `toBeChecked()` assertions. This was the only xplat/js-wide breakage from that diff—only bare `<Switch>` renders without explicit `accessible` props failed, and only in `TWInternBoolSettingComponent-test.js`.

Add an inline comment documenting the `testing-library/react-native` constraint to prevent future regressions. The four other component renames in D117877024 have no RNTL special-casing and remain as landed.
