Drop date-fns infavor of dayjs

[khavinshankar]

Both Day.js and date-fns provide similar functionality for date and time manipulation. We have decided to remove date-fns in favor of dayjs due to its minimal package size.

@khavinshankar
Day.js is 666kb,
date-fns is 22Mb
why are we removing Day.js? Is it because of more functionality? 😅

Oh my bad, I wrote it in reverse 😅
