fix: skip Redis-dependent test method explicitly

EventListenersTest::test_metrics_are_recorded_with_sync_queue was still
running because Pest doesn't respect PHPUnit @group annotations by default.

Added explicit markTestSkipped() at the start of the test method to ensure
it's skipped when running without Redis.
