Update pytest decoration

[snovikov]

Running on python 3.12.3 with pytest 8.2.1 I got this message:

PytestDeprecationWarning: The hookimpl ParallelRunner.pytest_sessionstart uses old-style configuration options (marks or attributes).
Please use the pytest.hookimpl(tryfirst=True) decorator instead
 to configure the hooks.
 See https://docs.pytest.org/en/latest/deprecations.html#configuring-hook-specs-impls-using-markers
  @pytest.mark.tryfirst

Thanks for opening a PR. Unfortunately, I'm no longer maintaining this project.

I'll be archiving the project.
