Pass a list to parametrize in test_docs_examples (pytest 9.1.0 compat)

pytest 9.1.0 deprecates passing a non-Collection iterable (e.g. a generator)
to pytest.mark.parametrize, raising PytestRemovedIn10Warning. With
filterwarnings = ["error"] this fails collection. find_examples() returns a
generator; materialize it as a list.

Same fix as #2889 on v1.x. main's CI matrix uses locked resolution so this
is not currently failing there, but it future-proofs against a pytest bump.
