Update URL to distutils configuration files docs (#6004)
## Summary
The existing URL 404s:
https://docs.python.org/3/install/index.html#distutils-configuration-files

has been removed:
https://docs.python.org/3.12/whatsnew/3.12.html#distutils

https://docs.python.org/3.11/install/index.html#distutils-configuration-files
