    Adwaita: Use variant-agnostic styling
    
    We use unsaturated selection style for sidebar rows to make it grab
    less attention. Since we use the light variant of Adwaita, we do this
    by making the colors darker using the shade() CSS color expression.
    
    However, this assumption breaks if the dark variant is explicitly set
    in Tweaks.
    
    While nautilus is not developed for the dark variant, this commit
    makes it work by deriving shading from other theme colors instead.
    
    Fixes https://gitlab.gnome.org/GNOME/nautilus/issues/630
