mypy failing when follow CONTRIBUTING instructions

[dschristianson]

Describe the bug
When pytest is run following the development configuration instructions in CONTRIBUTING (line 40), mypy fails.
The issue seems to be in calling mypy from pytest via the pytest.ini config.
Note that pytest seems to using plugin mypy-0.10.3 while when running separately, mypy version = 1.11.2.
See stack trace and more info below.

To Reproduce
Follow configuration instructions in CONTRIBUTING. I tested environments with python 3.8 and 3.10.

Expected behavior
All tests should pass.

Desktop (please complete the following information):

• Python 3.8 and 3.10

I tried a few things to troubleshoot:

1. With python 3.10, I changed the python version in the mypy.ini file.
2. I removed the --mypy option in the pytest.ini file to confirm that it was calling mypy from this mode. All other pytests pass.
3. Running mypy separately, all mypy checks pass.
