`pytest-codspeed` crashing since `pytest` 8.1.1

[davidhewitt]

PyO3 benches jobs in CI have recently started failing, somewhere in the pytest stage.

It looks like pytest 8.1.1 has changed something incompatibly with pytest-codspeed. I was able to fix the problem in PyO3's CI by pinning back to pytest < 8.1.

Here's a dump of the error:

I think this issue is related to pytest-dev/pytest#11785
Having a look rn
