ui/obs-browser-widget: Fix strange layout issue in Qt6

When a QCefWidget is alone and all by itself, no layout updates are performed on the "window". This causes a problem where it just stays in place, instead of moving with the rest of the elements. The fix to this appears to be to just add a different Qt widget into the layout.

Looks stupid, is stupid, but works anyway. Qt is weird.
