PHP 8.1 | Tests: temporarily ignore select test failure

The test failure being handled by setting an expectation for a PHP deprecation notice is on the list to be fixed via the "Filter extension"-CS action list.

Once the particular issue affecting this test has been fixed, the change from this commit should be reverted (and this is safeguarded by the expectation as the test will start to fail because the deprecation will no longer occur).
