Chat Participant doc nits

"They can choose to fully use AI for the query processing, or to forward the user request to a backend service."

Should also say that the participant can use local resources for query processing. iow, you don't have to use AI or a backend service, can use anything you want.

"Participants can also provide the language model access to tools. With the help of the language model, the participant might select a tool and define how to invoke it."

Other places in the document use upper case "Language Model".

"To help the user take the conversation further, participants can provide follow-ups for each response. "

Should we add a picture of a follow up, just for reference?

"Note: The Chat and Language Model API are finalized in VS Code Insiders and will be finalized in VS Code Stable release in July"

Should we say "July 2024"?

Image needs to be updated, we no longer overlap the GH icon and the chat participant icon.

" Chat participants are best when you want to control the full prompt, including the system message and instructions to the model."

Is "system message" the same as the "system prompt"? If so, we don't allow for this in the stable API so maybe remove this or caveat it?

We have a call-out for that in the chat user experience elements screenshot. I added a link to the section about registering follow-up questions.
