JSON type fix in Client and and typing fix for /chat endpoint in gr.ChatInterface

[abidlabs]

While working on the API for gr.ChatInterface, I noticed that the typing for the gr.JSON component was incorrect. I'm not sure why make a special case for the gr.JSON component in the first place (@freddyaboulton do you remember?) but at least we should fix the typing here.

Also replaces the gr.Textbox in gr.ChatInterface with gr.JSON so that it correctly states that dictionaries can be returned.

For example, the following chat interface is now correctly typed:

import gradio as gr

def fake(message, history):
    if message.strip():
        return {
            "role": "assistant", 
            "content": {
                "path": "https://github.com/gradio-app/gradio/raw/main/test/test_files/audio_sample.wav"
                }
            }
    else:
        return "Please provide the name of an artist"

_, url, _ = gr.ChatInterface(
    fake,
    type="messages",
    textbox=gr.Textbox(placeholder="Which artist's music do you want to listen to?", scale=7),
    chatbot=gr.Chatbot(placeholder="Play music by any artist!"),
).launch()

from gradio_client import Client

client = Client(url)
client.view_api()

(For more context, once we the API set up and typed correctly, I'll start working on the guides on how to deploy a Discord bot, Slack bot, etc. directly from a ChatInterface).

I guess we could collapse both cases into str | bool | int | float | list | dict since that covers the spectrum of possible json payloads
