[aur-requests] [PRQ#36022] Deletion Request for python2-corner

MarsSeed [1] filed a deletion request for python2-corner [2]: As python2-sncosmo has been deleted, this helper module has no use anymore on AUR. Supernova Cosmology packages support Python 3 only, so there is no point in keeping defunct Python 2 libraries around. So I suggest deletion. AUR has the Python 3 variant of this and of sncosmo.
