Upload emscripten wheels to PyPI

[oscarbenjamin]

@agriyakhetarpal now that PEP 783 for emscripten packaging is accepted does that mean that we can upload the pyodide wheels straight to PyPI?

I think that implementing this would just be a case of removing the rm line here and then making a new release:

python-flint/.github/workflows/buildwheel.yml

Lines 479 to 497 in d521145
