[aur-requests] [PRQ#15244] Deletion Request for ark-bin

tongpu [1] filed a deletion request for ark-bin [2]: ark is no longer being maintained and is superseded by velero. I maintain both ark-bin and velero-bin, so I believe we can remove ark- bin. [1] https://aur.archlinux.org/account/tongpu/ [2] https://aur.archlinux.org/pkgbase/ark-bin/
