Remove automatic .onion site prioritization instructions
In light of tpo/applications/tor-browser#42444 (closed), we need to update https://tb-manual.torproject.org/onion-services/
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.
