Subject: [PATCH] Let's pin in pyproject.toml too

Mostly since it's non-build-backend specific configuration and more
widely standardized file. Not sure what benefits pinning in setup.cfg
gives us on top of pyproject.toml but I'd rather not find out during
the release that is supposed to happen today :wink:
