This rule raises a diagnostic when there is a void [TestCleanup] method or on any [TestCleanup] if the targeted framework supports IAsyncDisposable interface.
Using Dispose or DisposeAsync is a more common pattern and some developers prefer to always use this pattern even for tests.
Replace [TestCleanup] method by Dispose or DisposeAsync pattern.
You usually don't want to suppress warnings from this rule if you decided to opt-in for it.
