    year-view: Change week numbers style
    
    Week numbers in year view was using a small and very light style and
    that was making difficult for users to be able to read it.
    
    After a few conversation with gnome-design team, they proposed the best
    approach it would be to use the same style as gnome-shell panel does.
    
    The week numbers style was changed to be as close as possible to the
    gnome-shell panel.
