`py.typed` missing from v34.0 wheel

[bhrutledge]

When attempting to use the new version in Twine, I got this error:

twine/commands/check.py:22: error: Skipping analyzing "readme_renderer.rst": module is installed, but missing library stubs or py.typed marker

It's in the sdist, but not the wheel:
