Most of the features for collab were previously listed in the section
that was written for private calls. Most of this PR is moving that
content over to the channel documentation and adapting it slightly.
Private calls have similar collaboration, so we can just point back to
the channels doc in that section and keep it pretty thin / DRY.
Release Notes:
- N/A
Overview
- Channels
- Private calls

Up next would be to
- [ ] Update any zed.dev links to point to items in this structure
- [ ] Update content in these docs (would prefer to do that in a
separate PR from this one)
Release Notes:
- N/A
