Next time we vendor pluggy, we should create an invoke task to do that automatically; also, the same task should update all internal links in the docs to point to the new location, for example:

same arguments as ``before`` but also a :py:class:`_CallOutcome`` object

To:

same arguments as ``before`` but also a :py:class:`_CallOutcome <_pytest.vendored_packages.pluggy._CallOutcome>` object
