packaging: upgrade packages in Windows environment

I ran `pip-compile -U` to update all packages to latest versions.
I did this so the Windows environment is more modern.

dulwich 0.20 dropped support for Python 2.7. Rather than add
yet another requirements.txt file, I decided to just pin at an
older release to minimize complexity.
