Measured time must include test setup/teardown

[mvorisek]

Currently the measured time does not include test teardown.

The solution is to drop
https://github.com/ergebnis/phpunit-slow-test-detector/blob/2.4.0/src/Subscriber/TestPassedSubscriber.php
as it is called in
https://github.com/sebastianbergmann/phpunit/blob/10.4.2/src/Framework/TestCase.php#L723
and use
https://github.com/sebastianbergmann/phpunit/blob/10.4.2/src/Framework/TestRunner.php#L238
"test finished" hook solely instead.

In "test finished" hook TestCase->status()->isFailure() && TestCase->status()->isError() can be used to filter out non-passing tests, but probably even non-passing tests can/should be reported if slow.
