Ensure HTML renders in gr.Chatbot

[hannahblair]

Description

The way Chatbot passes props to gr.HTML means we need to create a wrapper around HTML to get it working. This PR adds a wrapper around gr.HTML and changes the export path to that in package.json

Closes: #12595

demo:

import gradio as gr

with gr.Blocks() as demo:
    chatbot = gr.Chatbot()
    msg_textbox = gr.Textbox()

    demo.load(
        lambda: gr.update(value=[{"role": "assistant", "content": gr.HTML("<h1>Hello world!</h1>")}]),
        None,
        [chatbot]
    )

demo.launch()

Looks good but can you explain why the current approach doesn't work? The chatbot (should) load BaseHTML from @gradio/html. And here we're wrapping BaseHTML. Could we instead just change how the chatbot passes props to the html component in Component.svelte?
