From 5bae4e7b62996f1ef1b9ee6719581bde115d762c Mon Sep 17 00:00:00 2001

Subject: [PATCH] setup.py: make pkg_resources import optional for Python 3.12+
pkg_resources has been removed from newer Python/setuptools versions.
Wrap the import in a try/except block and guard the usage site,
allowing html5lib to build without pkg_resources present.
Upstream-Status: Pending
