Exclude Pyodide wheels from PyPI uploads (#375)

* Skip Pyodide wheels when uploading to PyPI

PyPI rejects wasm wheels with "unsupported platform tag
'pyodide_2024_0_wasm32'". Strip them from the dist/ directory before
publishing so the upload doesn't fail. The wheels are still built and
preserved as workflow artifacts so users can grab them from the run.

* Release 4.0.1

Bumps simplejson to 4.0.1 with a CHANGES.txt entry covering the PyPI
upload fix that skips Pyodide/wasm wheels (PR #375).

* Update Sphinx conf.py version to 4.0.1

conf.py was stale at 3.20.2 and got missed during the 4.0.0 bump.
