Fix documentation github action

[mogres]

Problem

The github action for documentation fails due to missing pkg_resources package.

Solution

Add setuptools to requirements. (Note, this is a workaround and pkg_resources is deprecated in python 3.12)

Type of change

• Bug fix (non-breaking change which fixes an issue)

Steps to Verify:

1. Merge PR into main branch
2. Github action for documentations should run automatically

The changes look reasonable to me, but I'm curious why the images failed to upload in the packing report for this pr.

@rugeli I am able to see the images on the web browser. Are they still not visible on your end?
