Deleting docs/js folder and extra_javascript in mkdocs.yaml

[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.
