[PRQ#48180] Deletion Request for python-galsim-extra-git

MarsSeed [1] filed a deletion request for python-galsim-extra-git [2]: Abandoned, broken Python2/Python3 VCS package from 2019. I recommend deletion, for lack of any maintainer's interest all these past years, and because nothing depends on it.
