about: Switch to AdwAboutWindow
as per !714 (comment 2075035) / closes #637
The application-name
property is not automatically inferred by AdwAboutWindow
; I had to add it. Previously the dialog said gnome-calls
. I used APP_DATA_NAME
here, which means it now shows up as calls
(note lowercase). Let me know if something else is preferable here.
