Decide what to do with the "Choose a bridge for me" button in Connection settings
Spin off from #42036 (comment 2974796).
When "about:torconnect" has failed to perform a regular Bootstrap we show in "about:preferences#connection" the location selector and a "Choose a Bridge for me..." button to open "about:preferences" and trigger "Auto-Bootstrapping". Once connected to tor, it won't show again.
We should decide on whether we want to drop this, or replace it with something else.
/cc @donuts do we want to do anything for 13.5?
