[CD] Remove scheduled Python wheel uploads.

While discussing #10371, we
considered removing the weekly dev wheel builds to save space on
PyPI. I think that is a great idea, so I'm just removing it here. We
can always add it back if needed, but I think they don't really serve
much purpose today anyway.
