Fix beartype crash on Windows by widening type hint to pytest.Item

The pytest_collection_modifyitems hook in vuforia_backends.py had
items typed as list[pytest.Function], but Sybil doctest items
(SybilItem) are also collected and don't inherit from Function.
The @beartype decorator enforced this at runtime, crashing the
Windows CI with a BeartypeCallHintParamViolation.
