[PRQ#53789] Deletion Request for nginx-quiche

MarsSeed [1] filed a deletion request for nginx-quiche [2]: Broken, unmaintained nginx variant from 2 years ago. Seems not useful to keep. Repo carries the latest nginx and nginx-mainline. Also AUR has additional maintained variants, both for stable and '-git' sources. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/nginx-quiche/
