Repurpose block-malicious-sites-checkbox on TLS error page in Tor Browser

Right now the checkbox on the neterror page sends a report about an TLS error to Mozilla (containing host, port, timestamp, useragent, update channel, buildid, certificate chain and version of that feature). We might want to repurpose that checkbox as, first, I see no reason why Mozilla should gather data related to a Tor Browser user. Second, this message is highly confusing in our context. Say, an exit node is MITMing a user. Why should the user report that to Mozilla in order to identify and block malicious sites? What is Mozilla supposed to do with that information?

We could think about having an own infrastructure for this that might help detecting bad relays

#32321 deals with Mozilla's MitM check pref. Might be interesting to think about that for ourselves.

Setting this at some time in the future. I can see us prioritizing this as it could leak onion addresses in self-signed certs (if I'm understanding this error case correctly). The exit-node-mitm situation is an interesting case, and Tor Browser providing a mechanism for people to report this is a neat idea.

Actually set it for some time in the future.
