Upgrade to new-style hook wrappers

Pytest 8 will use the [new-style hook wrappers](https://pluggy.readthedocs.io/en/stable/#wrappers) so we should add a version check to update the decorator for our `pytest_runtest_call` hooks.

See also: https://github.com/pytest-dev/pytest/issues/11714

Also re-enable the pytestdev test environment.

Start by reading the pluggy new-style hook wrapper documentation and the linked pytest issue, then locate the pytest_runtest_call hooks and the pytestdev test environment configuration. Update the decorator handling for the relevant pytest version and confirm that the pytestdev environment is enabled and passes.
