AdwWindow: Add close-with-escape property
I think it would be nice if AdwWindow
gained a property to close with Escape, as it is a common feature.
Context: In nautilus we are currently porting away multiple dialogs away from GtkDialog
. A common dialog feature is that they can be closed with Escape. To mimic the same behavior we add a shortcut block to the .ui file (I copied it from libadwaita IIRC).
