[PRQ#51307] Deletion Request for perl-json-pp

bence98 [1] filed a deletion request for perl-json-pp [2]: `perl` from [core] already provides this package, and the lastest version (4.16). This outdated package is no longer necessary, as pointed out in a comment from 2011. [1] https://aur.archlinux.org/account/bence98/ [2] https://aur.archlinux.org/pkgbase/perl-json-pp/
