[PRQ#52378] Deletion Request for swig3

MarsSeed [1] filed a deletion request for swig3 [2]: Unneeded, broken package for a legacy swig version from 2017. Was only created for the once already deleted AUR/armory from 2018, dead since 2019. Please see accepted deletion request for armory, PRQ#48074, and new deletion request for the still broken resubmitted package, PRQ#52375.
