Enhancement: Remove quit button from hamburger menu

[amethystgosling163]

You can misclick it while trying to quickly trying to open some option in the hamburger menu and that is why I think GNOME apps don't have the quit button in the hamburger menu and have the close button instead in the headerbar because then it is in a corner, and there it is much unlikely to be misclickable because of its position. That, and you take your cursor there intentionally to close the application.
