ENH: Consider warnings as errors when running pytest

Consider warnings as errors when running pytest.

I would suggest not adding -Werror for the min runs. Warnings are expected with old versions.

Tried different things here:

• aeacf9c: Adding --strict-warnings to [tool.pytest.ini_options] addopts did not work as the flag seemed not be understood by pytest:
  https://github.com/nipreps/nireports/actions/runs/12700037859/job/35401948885#step:12:42
• ed057ad: Adding -W error to [tool.pytest.ini_options] addopts results in pytest not bypassing the DeprecationWarning filtering rule in pyproject.toml and exiting without running all tests:
  https://github.com/nipreps/nireports/actions/runs/12700533251/job/35403381323
• aa05a60 : Adding -W error to the pytest command call in tox.ini results also in pytest not bypassing the DeprecationWarning filtering rule in pyproject.toml and exiting without running all tests.
  https://github.com/nipreps/nireports/actions/runs/12700597202/job/35403576905
• Ended up resorting to the ENH: Consider warnings as errors when running pytest nifreeze#40 solution: pytest fails with some other error
  https://github.com/nipreps/nireports/actions/runs/12700637456/job/35403696969#step:12:439

So ran out of ideas.

As for

I would suggest not adding -Werror for the min runs. Warnings are expected with old versions.

If you have a suggestion to avoid applying the option for them, I would be happy to add it.

You could do something like this in tox.ini:

command =
    pytest ... \
    !min:  -Werror \
      {posargs:-n auto}
