[PRQ#51211] Deletion Request for python-detectron2-git

MarsSeed [1] filed a deletion request for python-detectron2-git [2]: This VCS package is not worth keeping on AUR, for lack of user and maintainer interest for the last 2-3 years. It is also a heavy build, with a complex dependency chain. It's better if users acquire upstream's binary wheel, or the AUR/python-detectron2{,-cuda} PKGBUILD's third-party CI binary release.
