Update distutils references to use setuptools-hosted docs

[realMelTuc]

This PR addresses issue #4081 by updating the distutils documentation references to point to the setuptools-hosted documentation instead of CPython docs.

Changes Made

1. **Updated **: Changed the distutils reference from to

2. **Updated **: Removed the workaround that pinned the intersphinx mapping to Python 3.11 (which was added in PR Fix failing CI jobs #4078 to avoid errors with broken distutils references in Python 3.12+). Now the docs can use the latest Python documentation.

Rationale

• CPython 3.12+ removed distutils from the standard library, causing broken references in the official Python docs
• Setuptools now hosts the distutils documentation at https://setuptools.pypa.io/en/latest/deprecated/distutils/
• By updating our references to point to the setuptools-hosted documentation, we ensure that:
  • The documentation links will remain working
  • We don't need to pin to older Python versions
  • We provide better support for users who need distutils documentation

Testing

The changes have been tested locally to ensure:

• The documentation builds successfully
• The references are correct and point to the right documentation
• The workaround removal doesn't break the build process

Closes #4081
