[PRQ#50311] Deletion Request for gnupg23

MarsSeed [1] filed a deletion request for gnupg23 [2]: EOL since 2022-12, as v2.3 was not an LTS release. Also pkgname does not conform to Arch package guidelines that call for attaching only the major version number to the name (otherwise one should add dots, for e.g. 'gnupg-2.3'). Safe to delete this unsafe, unneeded package. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/gnupg23/
