Remove pytest.deprecated_call() in TestAssoc::test_unknown (#1249)

assoc() no longer raises a deprecation warning since commit
22ae847 but the 'with
pytest.deprecated_call():' in that test was not removed then (in
contrast with other test cases).

Maybe this got unnoticed due to a pytest bug?
In any case, using pytest 8+ (and keeping deprecated_call()) shows that
no warning is raised and the test fails.

Removing the upper bound on pytest in dev dependencies as tests now
pass with pytest 8.0.

Fix #1233.
