Stop using custom buttons for notification actions. The only reason to use custom buttons was so that we could add icons next to the button label, if we really need the icons next to the label we can add icons to the notification API. By using the actions API we can ensure that buttons always look the same without additional work. Part-of: <https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/3173>
