[PRQ#58956] Deletion Request for gtk3-nocsd-git

dreieck [1] filed a deletion request for gtk3-nocsd-git [2]: I disowned this, since [`gtk3-classic`](https://aur.archlinux.org/packages?K=gtk3-classic) is there to provide this functionality, and it is maintained upstream, contrary to `gtk3-nocsd`-upstream. To not confuse users I propose deletion as well. [1] https://aur.archlinux.org/account/dreieck/ [2] https://aur.archlinux.org/pkgbase/gtk3-nocsd-git/
