Fix update dependencies problem.

When safety is updated from 2.3.4 to 2.3.5 (its latest release), a dependency resolution problem occurs:

    black 23.7.0 depends on packaging>=22.0
    build 1.0.0 depends on packaging>=19.0
    pytest 7.4.1 depends on packaging
    safety 2.3.5 depends on packaging<22.0 and >=21.0

Perhaps the answer is to just wait, but, whatever the answer is, it would be nice to be able to use the latest version of each of our dependencies.
