pyproject.toml: use ~= for dependencies

These are the closest to semantic versioning in Python that I can
find with PEP 621 syntax. For example:

> ~=3.1: version 3.1 or later, but not version 4.0 or later.
> ~=3.1.2: version 3.1.2 or later, but not version 3.2.0 or later.

For most cases I want to bump the minor and micro / patch.
