chore: add py3 and cz to default tox environment list

JohnVillalovos · JohnVillalovos · commit a8855a831b72 · 2022-05-05T08:26:02.000-07:00
The `py3` tox environment will run with the system default Python
version.

Also remove all the version specific Python environments as it is
confusing when they fail.

The CI and users can still run the version specific Python
environment.  For example to run the Python 3.7
environment: tox -e py37
diff --git a/tox.ini b/tox.ini
