refactor: propose enhancement for calendar 0.1.0

[sunjungAn]

Description

This PR refactors the calendar component to make the code more concise. By leveraging date-fns, we’re now offering more intuitive internationalization. Additionally, a styles prop has been introduced, allowing for customization of all sub-component styles.
To optimize the scrolling experience, the implementation now utilizes FlatList, ensuring smoother horizontal transitions. However, a limitation was encountered with scrollToIndex in FlatList, which didn’t trigger as expected. As a workaround, and as documented in the comments, we’ve implemented the onScrollToIndexFailed solution suggested in this Stack Overflow post.
Lastly, updates have been made to CalendarCarouselBasicStory to reflect the current changes.

Test Plan

You can test by injecting props into CalendarCarouselBasicStory. Currently, it’s a very basic version, and you can primarily try making style-centric changes.
