run test session against active python versions

How would this feature be useful?

Hi, thanks for this package, it solves many issues I had with tox.

Many times ago I've developed a package that can be useful while working with nox, it is python-active-versions that gather python's active versions from developers website.

It can be used together with nox in a way like this:

import nox

from python_active_versions.python_active_versions import get_active_python_versions
from typing import List

def _get_active_version(_active_versions: List[dict]) -> List[str]:
    return [_av['version'] for _av in _active_versions]

_python_versions = _get_active_version(get_active_python_versions())

@nox.session(python=_python_versions)
def test_something(session):
    ...

@nox.session(python=_python_versions)
def test_another(session):
    ...

So nox executes test sessions against installed and active (not EOL) python versions; devs have no more need to manually put supported python version array to the session.

Hope this can be useful for other python devs that are using nox.

Thanks.
