Remove "Prioritize .onion sites when known." instructions
Due bug https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/42444, "prioritize .onion sites" option was removed from Tor Browser. We need to update the TB-Manual to reflect this:
To always prioritize onion site versions of websites, you can enable automatic Onion-Location redirects. Click on hamburger menu (≡), go to Settings, click on Privacy & Security, and in the Onion Services section look for the entry "Prioritize .onion sites when known." and check the option "Always". Or you can copy and paste this URL in a new tab: about:preferences#privacy and change this setting.
