[nautilus/wip/cdavis/use-flap: 2/2] general: GtkPaned -> AdwFlap




commit 2f9d8f39ae61fbcb43a704a94ca12ccea1b7a54f
Author: Christopher Davis <christopherdavis gnome org>
Date:   Sat Jul 9 12:38:10 2022 -0400

    general: GtkPaned -> AdwFlap
    
    Exchange the adjustable GtkPaned widget for AdwFlap. We lose
    a resizable sidebar, but gain an adaptive one.
    
    The loss of the resizable sidebar means that all settings related
    to it are removed.
    
    Fixes #2156
