exclude 32-bit Windows artifact in download-workflow-artifacts.sh

This helps ensure the identically-named 32-bit tarfile doesn't overwrite the
64-bit one when we extract everything into a single directory.

I'll follow this up by making an updated wasi-sdk-22.0.m-mingw.tar.gz and adding
it to the wasi-sdk-22 release.

Fixes #326
