Fix python requirements problem

The dependabot report two security problems for python requirements

gitpython <= 3.1.20
certifi < 2022.12.07

And there is also a parse error

InstallationError("Invalid requirement: 'cryptography=3.3.2' (from line 22 of /home/dependabot/dependabot-updater/dependabot_tmp_dir/requirements.txt)\nHint: = is not a valid operator. Did you mean == ?")
