[aur-requests] [PRQ#7471] Deletion Request for singularityviewer32

GordonGR [1] filed a deletion request for singularityviewer32 [2]: It doesn't seem like anyone uses the 32-bit version of Singularity any more. Upstream has stopped producing it (with promises that it will return at some point, but it's been many months now). Combine that to the i686 phasing out, and I think we can safely delete this package. [1] https://aur.archlinux.org/account/GordonGR/ [2] https://aur.archlinux.org/pkgbase/singularityviewer32/
