Update to JUnit 5.13+

[trancexpress]

JUnit 5.13.0 has two new annotations: @ParameterizedClass and @ClassTemplate

Those annotations can be used to repeat test cases, something that was missing so far with JUnit 5, see e.g.: junit-team/junit-framework#4608

It would be good to have the newer JUnit 5.13 in Eclipse, currently the Eclipse SDK comes with JUnit 5.12.2 resp. 1.12.2.

Will be fixed by: #3067

JUnit 5.13 is in latest I-build now.
