Document "WebRTC: Browser to Server"

[p-shahi]

libp2p maintainers have specified and are adding support for the Browser to Server aspect of the WebRTC transport protocol across three implementations:

• The Working Draft version of the specification is merged: webrtc/: Add libp2p WebRTC browser-to-server spec specs#412
• Per the working draft, three libp2p implementations are estimated to add support by end of Q4 2022 (go-libp2p, js-libp2p, and rust-libp2p) (✅ rust-libp2p has been merged)
• WebRTC interoperability testing across implementations is also starting mid Q4

Done Criteria

• Documentation for "WebRTC: Browser to Server" exists under the "Transports" section
  • describes WebRTC in general
  • describes WebRTC Browser to Server in libp2p
  • compare/contrast with what WebRTC offers vs other supported transports
  • acknowledges WebRTC Browser to Browser is not yet fully specified/implemented

Why Important

Expanding the ways libp2p enables connectivity (beyond standalone nodes and into browser connectivity) is a primary goal of the libp2p project, WebRTC is center to that.
As we finish specification and implementation, we need corresponding documentation for the transport and it's use-cases.
