```
it is a regression from https://github.com/facebook/react-native/issues/46123 that to have a lazy require.
this pr tries to mock `useColorScheme` to return `light`. i think we don't necessarily test the color scheme changes in jest runtime. originally `useColorScheme` also returns `light` because of [this statement](https://github.com/facebook/react-native/blob/9a60038a40e16925ea1adeb3e3c937c22a615485/packages/react-native/Libraries/Utilities/Appearance.js#L77-L83)
## Changelog:
