Risky errors when there are no assertions are added before the test end listeners are called (ie, before the code in endTest is executed) so forcing beStrictAboutTestsThatDoNotTestAnything to false when there is a expectedDeprecation annotation is enough.

If the goal is to reset the value to the original value, then I think we should not do it since we basically "lie" to the next listeners. Let's assume that when a test expect a deprecation, it can have 0 assertions. Also this flag is not used anymore by PHPUnit after we reset it.

Ref #21786 btw
