Python 3.11 - doctest failure related to enhanced tracebacks

[hrnciar]

BUG/PROBLEM REPORT (OR OTHER COMMON ISSUE)

What I did:

Built zope.testing with Python 3.11

What I expect to happen:

Successful build

What actually happened:

Build failed. I think this is because the enhanced tracebacks in Python 3.11. I was able to fix it with a dirty patch conditionalizing doctestcase.txt file based on python version.

See downstream PR is Fedora: https://src.fedoraproject.org/rpms/python-zope-testing/pull-request/3

What version of Python and Zope/Addons I am using:

Fedora Rawhide Python 3.11.0b3 zope.testing 4.7
