accessibility: mui react table missing semantic

What you were expecting: As a blind user relying on screenreader and Braille display, I expect clickable elements to be shown as either links or buttons.

What happened instead: Clickable table rows in MUI react tables are shown as normal text, although they do execute an action when enter is pressed on them.

Steps to reproduce:

1. Go to the helpdesk demo on (https://marmelab.com/react-admin-helpdesk/#/tickets)
2. Turn on a screenreader, tested with NVDA on Windows
3. Navigate the tickets table
4. Find that entries are neither links nor buttons, but execute when pressed
