Do not inherit text-decoration on <a>

[sambostock]

Description

It seems reasonable that by default links should be decorated (underlined), and that undecorated links are the special case, not the other way around.

Closes #837 (tentatively

I'll try to get to this before the end of the week. I don't have any issue with the code but this could break the UI anywhere we are using an anchor tag for anything, so will need thorough testing.

As an aside, are we sure #837 is still present? The HTML component gets the prose class added (https://github.com/gradio-app/gradio/blob/main/ui/packages/html/src/HTML.svelte#L14) and .prose a has text decoration (https://github.com/gradio-app/gradio/blob/main/ui/packages/theme/src/typography.css#L170-L175)

Tested, you're right @pngwn links show up just fine:

import gradio as gr

with gr.Blocks() as demo:
    gr.HTML(
"""
Visit <a href="www.google.com">www.google.com</a> and click <button>here</button>
""")
    
demo.launch()

Looks like we can close this PR and the underlying issue (#837). Also tested a related issue (#2520), which I can confirm is still open on the latest version of gradio.

Awesome.
