[PRQ#51551] Deletion Request for perl6-http-hpack

MarsSeed [1] filed a deletion request for perl6-http-hpack [2]: Cleanup of Perl6 based cro (PRQ#51534) from 2018: broken, abandoned on AUR, just like almost all of its dependencies. Also Perl6 is now Raku, so pkgname prefix should reflect that. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/perl6-http-hpack/
