[feat]: Make date picker calendars move individually

[Keith-Web3]

Feature description

The current way the datepicker moves is weird and quite confusing for users. Whenever one of the calendars is moved, the other follows and so there's always a one month gap between the two. It would be better if the calendars could each have their own set of carets to navigate to different months.
Below is a video that shows the behaviour I'm talking about

If you only need a single date picker (not a range), the component below might be useful:
