[PRQ#51439] Deletion Request for perl6-pod-to-html

MarsSeed [1] filed a deletion request for perl6-pod-to-html [2]: Abandoned, unused Perl6 package from 2017. (Also these should now have the 'raku-' prefix in pkgname.) Safe to delete, as nothing depends on it. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/perl6-pod-to-html/
