Context Navigation

Changes between Initial Version and Version 1 of Ticket #35874, comment 11

initial	v1
9	9	3. No keyboard navigation support (selecting a tab currently requires a pointer device)
10	10	4. Choice of tab is not synchronized/persistent (so Windows users have to activate their preferred tabs repeatedly on pages with multiple console examples, or after navigating; solution would require JS)
	11	5. The use of `text-align: right` and `text-align: left` ''probably'' causes problems for rtl
11	12
12	13	My PRs for #37138 only solve the first problem right now, and only because I needed to get rid of the fa-brands fonts while adapting the djangodocs extension to the other Sphinx themes. I'd defer to any progress James has made on tab accessibility in general. (But if the scope of console-tabs changes in the other ticket starts to grow, I'll come back and claim this ticket too.)
