Make bridge lines address into 'human-memorable' address or easier for users to copy/share

A frequent problem in our user support channels is users failing to add a new bridge due to various reasons:

• Sometimes they just copy a piece of it (IP:Port) (tpo/applications/tor-browser#40552 (closed))
• In other cases they were adding more than one bridge without the right space/delimiter and then Tor fails to parse it right.

There are other instances where these poorly formatted addresses result in the user being unable to connect to Tor and lead them to report that the bridge is blocked in their country. (cc: @nina @championquizzer)

This is affecting users especially from high censored regions because we're sharing private bridges with them as other pluggable transports didn't work for them.

Maybe qr-codes could be used with bridgemojis? Maybe bridges with human-memorables address would make this easier?
