nixos/tests/sway: test GPG's pinentry pop-up

This test is important to confirm that $WAYLAND_DISPLAY is correctly
imported via "dbus-update-activation-environment --systemd" which is
done by default since #122605 (00e8e5b123f).
It ensures that the gnome3-pinentry pop-ups work as expected to avoid
regressions like #119445 (which also broke screen sharing).
