[PRQ#48628] Deletion Request for python2-networkx

MarsSeed [1] filed a deletion request for python2-networkx [2]: Cleanup of unneeded Python2 packages. python2-shaape-git is broken on Python 2.7 and not maintained since 2014. So after its deletion (PRQ#48507), it's safe to drop this as well. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/python2-networkx/
