add a schema version on releases of NMDC schema about nmdc-schema

[dwinston]

@wdduncan I'm familiar with the following scheme (which I used for https://github.com/polyneme/nmdc-mongo-tools):

# among dev requirements
invoke
setuptools-scm
twine

# in /setup.py

from setuptools import setup, find_packages

setup(
    packages=find_packages(),
    use_scm_version=True,
...

# in /tasks.py
from subprocess import run

from invoke import task


@task
def publish(c):
    completed = run(
        "git describe --tags $(git rev-list --tags --max-count=1)",
        shell=True,
        capture_output=True,
        encoding="utf-8",
    )
    vtag = completed.stdout.strip()
    major_minor, dot, patch = vtag.rpartition(".")
    vtag_new = major_minor + dot + str(int(patch) + 1)
    run(["git", "tag", vtag_new])
    run(["git", "push"])
    run(["git", "push", "--tags"])
    c.run("rm dist/*.*", warn=True)
    c.run("python setup.py sdist bdist_wheel")
    c.run("twine upload dist/*")

Here, invoke publish on the command line bumps the patch version via a git tag and pushes that to PyPI. The logic above can be refactored to use calver (e.g. YYYY.MM.DD).

The nmdc-schema is now versioned using pypi.
