Describe the feature you'd like

The way the language selection menu in the user settings page currently is in Lemmy-UI is really confusing and unintuitive. I recommend changing it to a simple scrolling list with checkboxes. That way it is easier to select and deselect languages from the menu.

Image for context so people know what I'm talking about.

I know this is low priority, and other UIs can take care of it anyway, but it probably should still be addressed anyway, eventually.
