Adding some notes here to declare what are the changes to the older files and newer files.

Check https://github.com/JessicaTegner/pypandoc/actions/runs/3343755281 to see the generated wheel files in the artifact
I disabled the if: github.ref == 'refs/heads/master' filter to test.

Generates files:

• pypandoc-1.9.tar.gz - Same as earlier, uses setup.py command to create file ☑️
• pypandoc-1.9-py3-none-any.whl - Same as earlier, uses setup.py command to create file ☑️
• pypandoc_binary-1.9-py3-none-win32.whl - Identical to earlier file - generated using cibuildwheel now. I don't have a win32 machine and so unable to test it. But it is identical to the older wheel for win32 ☑️
• pypandoc_binary-1.9-py3-none-win_amd64.whl - New file - similar to win32. Tetsted with my local windows - works fine. ✅
• pypandoc_binary-1.9-py3-none-macosx_10_15_x86_64.whl - Not generated anymore (see next line) ❌
• pypandoc_binary-1.9-py3-none-macosx_10_9_x86_64.whl - New file - similar to 10_15 but now supports older MacOS versions ^_^/ I don't have a mac and so unable to test it. But identical to the older wheel for macos ☑️
• pypandoc_binary-1.9-py3-none-manylinux_2_5_x86_64.manylinux1_x86_64.manylinux_2_17_x86_64.manylinux2014_x86_64.whl - New file. Tested with my local ubuntu 18.04 works fine and can support older linux versions also ✅
• pypandoc_binary-1.9-py3-none-musllinux_1_1_x86_64.whl - New file - I tested this in an alpine docker image - worked. ✅

✅ - I have tested it manually and it works
☑️ - I have not tested as I can't create the setup. But I compared it with previous files and it is identical
❌ - Does not require testing

@AbdealiJK phenomenal work. After merging, the "latest" tag should hold the newly generated wheels. Can you confirm that they work, and if they do, I'll publish a new version to pypi.
Again fantastic work. Thanks so much! :)

Thanks for the amazingly quick responses @JessicaTegner

I tested all the packages I could (i.e. everything except win32 and macos)
All looks good.
