Anders Kaseorg a3d26d701e styles: Rename .scss files back to .css.
css-loader@4 broke @import statements referencing files with
extensions other than .css, unless those @import statements are
compiled away by another loader.  Upstream is more interested in
arguing that such @import statements are semantically incorrect than
applying the one line fix.
