Describe the bug
When a screenreader user arrows through the content in the datepicker, the screen reader reads the calendar header's days of the week as "Su" "Mo" "Tu" We" (I tested with voiceover)
To Reproduce
Steps to reproduce the behavior:
1)Go to the react-datepicker demo (https://reactdatepicker.com/)
2)Turn on a screenreader (I used Voiceover)
3)Arrow through the calendar to the days of the week at the top and observe how they are announced by the screen reader
Expected behavior
It would be better if either:
1)The weekdays had aria-labels and were read by the screen reader as "Sunday" "Monday" etc.
2)These elements were skipped over altogether (aria-hidden=true) since the actual dates are read as "Sunday August 1 2021" and already include the day, so being able to focus on the weekdays isn't really useful.
