Chatbot does not show PDF file

[taoari]

Describe the bug

For gr.Chatbot(), If the response is a PDF (or other) file, the chatbot does not show anything.

import gradio as gr

with gr.Blocks() as demo:
    gr.Chatbot([
        (None, ("https://upload.wikimedia.org/wikipedia/commons/5/53/Sheba1.JPG",)), 
        (None, ("https://upload.wikimedia.org/wikipedia/commons/2/28/Caldhu.wav",)), 
        (None, ("https://www.africau.edu/images/default/sample.pdf",)), 
        (None, ("https://raw.githubusercontent.com/alecjacobson/common-3d-test-models/master/data/stanford-bunny.obj",)),
        (None, ("https://raw.githubusercontent.com/gradio-app/gradio/main/package.json",)), 
        (None, ("https://raw.githubusercontent.com/gradio-app/gradio/main/render_readme.py",)), 
    ]).style(height=1000)

demo.launch()

For the gr.File() widget, it actually shows the file name, file size, and download button. Can the chatbot at least do the same?

@taoari At the moment, chatbot supports images, audio, and video file types. You can provide your files as links as part of a regular chatbot message and the links will show up

I think it'd be good to add general file support to chatbots -- we don't need the preview, but at least we could have the basic file info. WDYT @dawoodkhan82?
