Refactor: Extract Arrow and Indicator components from Carousel

This commit extracts the arrow and indicator rendering logic from the main Carousel component into dedicated `Arrow` and `Indicator` components.

- I created `src/components/Carousel/Arrow.tsx` for arrow controls.
- I created `src/components/Carousel/Indicator.tsx` for indicator dots.
- I updated `src/components/Carousel/index.tsx` to use these new components by modifying `defaultProps` for `renderArrowPrev`, `renderArrowNext`, and `renderIndicator`.
- I reverted an unintentional modification to the `scripts.format` in `package.json` back to its original state.

This change improves code modularity, readability, and reusability of the arrow and indicator UI elements.

All existing tests pass, and snapshots have been updated accordingly.
