Replace pytest_ordering with pytest_order

pytest_ordering seems unmaintained as it hasn't been updated in two years: https://github.com/ftobia/pytest-ordering. It is also broken, at least in Nixpkgs: https://github.com/NixOS/nixpkgs/pull/122264.
pytest_order is a maintained and working fork.
I added a similar patch to Nixpkgs a while ago to make it work there: 6965eef223/pkgs/development/python-modules/ipfshttpclient/default.nix (L59-L63).
