Bring back voice channel linking

With the implementation of server video, linking to voice channels got removed.

Back then you could link voice channels just like text channels via this link template: "https://discordapp.com/channels/SERVERID/VOICECHANNELID"
It would highlight the linked voice channel but not let you join, like an invite would.
People told me, this was unintended behavior, but voice channel links behaved just like text channels.

Yes invites could be a substitute, but they 1) join automatically when clicked 2) open your server to the outside, if you want to use VC links
