Current behavior
When clicking on the table header (multi sort options) that is currently in "ascending" order, the aria-sort value is still "ascending".

Expected behavior
The value of the aria-sort must change to "descending"

Minimal reproduction of the problem with instructions
It can be reproduced directly on the demo (v12.2.4):

All accessibility issues will be fixed in 2022 Q1. We're gonna publish accessibility scores as well. Thanks for your report.

I am still experiencing this issue on v18, and can also reproduce it on the PrimeNG showcase page with the same steps: https://primeng.org/table#multiple-columns-sort
