Delete js folder and remove extra_javascript

[MhmoudGit]

Summary

I found an issue about the chat button not working on website and there was a suggestion to remove the docs/js files.
So I deleted the extra_javascript in mkdocs.yaml and the js folder altogether.

Impact

This will remove the "Open Chat" button from the docs website.

@MhmoudGit thanks for contributing. Which issue are you referring to?

Hi @zanieb, I did the same PR regarding issue #2303 on starlette and @Kludex asked if I can do the same PR in uvicorn and httpx so I did this one and on httpx as well.

Can we link the other PRs here? 👀

[MhmoudGit]

The one on httpx was approved, merged and closed so only this and starlette are opened for now.
Do you mean I should put a link here? or that question wasn't for me? 😅
