Bug 1815635 [wpt PR 38410] - Fix shadow-dom/focus-navigation/focus-na…

…vigation-web-component-input-type-radio.html for Safari, a=testonly

Automatic update from web-platform-tests
Fix shadow-dom/focus-navigation/focus-navigation-web-component-input-type-radio.html for Safari (#38410)

This test was erroneously assuming that radio buttons are focusable.
Use a span with ARIA role=radio and tabindex=0 instead as this is not the case in Safari.

Also rename the test accordingly.
