Upgrade sqlalchemy-oso's packaging version to support newer / more modern versions of Black

[kkirsche]

To support updates to tools such as Black, sqlalchemy-oso needs to loosen its packaging dependency restrictions:

Because no versions of black match >23.1.0,<24.0.0
 and black (23.1.0) depends on packaging (>=22.0), black (>=23.1.0,<24.0.0) requires packaging (>=22.0).
And because sqlalchemy-oso (0.26.3) depends on packaging (>=21.3,<22.0)
 and no versions of sqlalchemy-oso match >0.26.3,<0.27.0, black (>=23.1.0,<24.0.0) is incompatible with sqlalchemy-oso (>=0.26.3,<0.27.0).
So, because PROJECT_NAME depends on both sqlalchemy-oso (^0.26.3) and black (^23.1.0), version solving failed.

Black now depends on packaging version 22.0 or later. This is required for new functionality that needs to parse part of the project metadata (psf/black#3219)
