Simple uv-based release script

release.sh

#!/usr/bin/env bash
#
# Release the project and bump version number in the process.
#
# To set up the project, make sure you have in pyproject.toml:
#
# [project]
# name = "foo-bar"
# version = "2.10.0"
# ...
# [project.scripts]
# foo_bar = "foo_bar.__main__:main"
# # make uv build the project before running
# [build-system]
# requires = ["uv_build>=0.7.13,<0.8.0"]
# build-backend = "uv_build"
# 
# # set the module path to the root of the project instead of "src" (default)
# [tool.uv.build-backend]
# module-name = "foo_bar"
# module-root = ""
#
# And in `foo_bar/__init__.py`:
#
# from importlib.metadata import version
#
# __version__ = version("foo-bar")
