Added many PeerTube channels to PieFed

Thanks to amazing work by @andrews@piefed.social, PieFed can now federate with PeerTube - channels from a PeerTube instance show up as communities in PieFed and each video is a post which can be voted on and commented on.

To get things started I've done a bit of crowdsourcing and added all the interesting, active and cool PeerTube channels I could find! Check these out:
