JS client documentation is missing a lot of content

[pdaoust]

Whilst perusing the generated JS client documentation, I discovered that there's a lot of empty stubs in there. There could be a lot of useful information re: usage in there.

I suspect there needs to be a spike first, to determine how much of the documentation is just stubs or insufficiently filled out content.

Spike completed. Issues I identified:

• Conductor APIs not documented beyond a stub sentence. Tracking in Link from JS client API endpoint functions JSDoc to holochain_conductor_api rustdoc #290.
• Types deserve some documentation; at first I think we should point to the Rustdoc similarly to Link from JS client API endpoint functions JSDoc to holochain_conductor_api rustdoc #290.
• Interfaces should either be suppressed from generated documentation or have boilerplate text pointing to an implementation (e.g., AppClient.* → AppWebSocket.*)
• References to other types sometimes don't exist (e.g., https://github.com/holochain/holochain-client-js/blob/main/docs/client.adminwebsocket.addagentinfo.md ) -- not a widespread problem, but needs a combing.
