Should document stability of diagnostics_channel publishers.

[Qard]

There is a growing list of channels listed in the diagnostics_channel documentation, but they lack any indication of their stability level. We should probably mark them all as experimental and then review if any should be promoted to stable. I'm leaving this here as a good-first-issue for someone to do the first step of marking them all as experimental.

hey Qard , I would like to take this up

[RaisinTen]

Are you referring to the built-in channels list at the end? Those are all marked experimental as a whole already.

[Qard]

Yes, that's what I'm referring to. Those should be marked individually as experimental as with functions so we can begin promoting some of them to stable.

[RaisinTen]

Thanks for clarifying, that makes sense.
