Upgrade pinned dependencies to the latest version
These versions were obtained by:
- Dropping all the pins in requirements/base.txt and prod.txt
- Setting the Docker image to python:3.10-slim
- Running a complete install to get the latest version of everything
- Running
pip freeze
to lock down the versions.
Note that with these newer versions it no longer seems to be necessary to separately install cython & cryptography in the Dockerfile.
