Latest release does not contain a wheel

[miketheman]

This is a repeat of #42 https://pypi.org/project/mypy-zope/1.0.5/#files shows only an sdist

Prior releases have a wheel: https://pypi.org/project/mypy-zope/1.0.4/#files https://pypi.org/project/mypy-zope/1.0.3/#files

Might be worth looking into having GitHub Actions publish the releases? https://docs.pypi.org/trusted-publishers/
