Release dance for a python package with hatch

hatch-release.sh

#!/bin/bash
# Generic "Bump version, update changelog, git tag, upload to pypi, bump version" workflow,
# like zest.releaser+setuptools, but for hatch+towncrier
# Matching pyproject.toml example: https://github.com/wosc/nginx-db-auth/blob/1.1.0/pyproject.toml
# (the salient points are 1) `hatch run release:towncrier`, 2) `dynamic = ["version"]`, 3) file locations for changelog and version)
