Remove astropy test runner and other updates (#185)

* Stop using _astropy_init.py

* Delete astrowidgets/_astropy_init.py

* Delete astrowidgets/conftest.py

because we do not use astropy test runner, so root level copy is enough

* Update setup.cfg

* Update tox.ini

* TST: Bump Python versions

* Update ci_workflows.yml
