Improve a11y of survey page

Fixes #19219
This PR improves a little bit score picker component at survey page. Before we had picker with links inside to pick a score, now we have picker with radio buttons group and wrapper with arial-label for this group which is good because now it's much easy to navigate with keyboard and voice over does his job properly (see video below for example)
Also turned out we have autofocus on first textarea at survey page which is useful because user wants to fill survey fields first before using main code search. But this thing did't work properly because we had autofocus: true on main nav search at header on this page as well. So there was autofocus problem which this PR solved as well.
