Incorrect error message in pickling test for Python 3.12 in Debian

[NGC2023]

Hi, The test_pickling_subclassed_schema__issue_263 test fails in Python 3.12 during build in Debian due to a change in the error message format for pickling failures. The test is currently expecting an outdated error message. It needs to be updated to reflect the new error message format to correctly handle and verify pickling errors for subclassed XML schema objects.

Hi, it should be in Debian sid i suppose. The change is in Python 3.12.5, i will add a condition on sys.version_info for this test.

Thank you
