Bug description

Chat bubble icon in left side bar is missing

This was broken in #312. Previously it looked like

The problem is the relative link in https://github.com/Quansight/ragna/blob/0cb205f24ca9fb322ac32a2e1aaec6b34928cd2e/ragna/deploy/_ui/css/left_sidebar/button.css#L27

How to reproduce the bug?

Open the web UI and look at the left sidebar

Versions and dependencies used

main after #312

Using url("../../imgs/chat_bubble.svg") is a fair way to have it working. Another solution is to have the image base64-encoded in the CSS, but we don't want that.
