Test failure in test_repr_with_name with Python 3.12.0

Hi,

When building pytest-mock in python 3.12.0:

FAILED ../../../tests/test_pytest_mock.py::TestMockerStub::test_failure_message_with_no_name - AssertionError: Regex pattern did not match.
FAILED ../../../tests/test_pytest_mock.py::TestMockerStub::test_failure_message_with_name[None] - AssertionError: Regex pattern did not match.
FAILED ../../../tests/test_pytest_mock.py::TestMockerStub::test_failure_message_with_name[] - AssertionError: Regex pattern did not match.
FAILED ../../../tests/test_pytest_mock.py::TestMockerStub::test_failure_message_with_name[f] - AssertionError: Regex pattern did not match.
FAILED ../../../tests/test_pytest_mock.py::TestMockerStub::test_failure_message_with_name[The Castle of aaarrrrggh] - AssertionError: Regex pattern did not match.

Looking into the issue, seems #404 caused test failure.

The change in python (python/cpython#111019) mentioned in #404 was backported to python 3.11.7 and 3.12.1, causing Python 3.12.0 fails.

I see, thanks for reporting.

TBH I don't intend to have the test suite working on every minor version of Python, supporting the latest one is enough in the context of this project.
