Include 6 in junit.platform import version range

[chrisrueger]

Closes #7052

Updated the Import-Package directive to limit org.junit.platform.* to versions below 7, ensuring compatibility with supported JUnit Platform versions including to Junit6. This is because of JUnit6's new version scheme where all versions now start at 6.x : https://github.com/junit-team/junit-framework/wiki/Upgrading-to-JUnit-6.0#new-versioning-scheme

This creates the following Import-Package for biz.aQute.tester.junit-platform.jar

Bundle-Description                      A bnd tester using JUnit Platform. Like biz.aQute.tester, this bundle will add itself to the -runbundles at the end. At startup, this bundle will then look for TestEngine implementations among the loaded bundles and use them to execute the tests. This bundle does NOT contain the necessary TestEngine implementations for JUnit 3, 4 or 5 - it will import them just like any other bundle.

Converted back to draft. I did some local tests with the tests of bnd's testsuite itself and tried to upgrade it to JUnit6. All tests failed. It turns out JUnit6's OSGi headers are different so that the range expansion alone is not enough.

Example junit-platform-commons:

JUnit Platform 1.10.1

just had

Export-Package: org.junit.platform.commons.util
  version=1.10.1
  status=DEPRECATED

JUnit Platform 6.0.2

has

Export-Package: org.junit.platform.commons.util
  version=6.0.2
  status=INTERNAL
  mandatory:=status

Notice the mandatory:=status.
This means that consumers ( biz.aQute.tester.junit-platform) now also need to explicitly query the status attribute=INTERNAL in the filter (basically saying: "I really really want this evil INTERNAL stuff").
e.g.

I could make some tests pass by explicitly filtering for the status=INTERNAL

Import-Package: org.junit.platform.commons.util;status=INTERNAL;version="[6,7)";resolution:=optional, \
	org.junit.platform.*;version="${range;[==,7);${junit.platform.tester.version}}",\

instead of just

Import-Package: org.junit.platform.*;version="${range;[==,7);${junit.platform.tester.version}}",\

(without the status=INTERNAL filter)

But I am not sure and there were still some tests which did not work. I guess because there is more similar stuff like org.junit.platform.commons.util which I didn't identify yet and which leads to different classloading effects so that some packages of JUnit are coming from JUnit5 and some from Junit6 which create a mess. Note might only be a bnd problem because in our testsuite we have multiple JUnit versions available at the same time. So having a single large filter for like ${range[==,7);${junit.platform.tester.version}} (which basically is [1.10.1,7) is not enough anymore and really hard to reason about.

Long story short: I think biz.aQute.tester.junit-platform is not yet compatible with JUnit6.
Maybe we need a new biz.aQute.tester.junit-platform-junit6.

@kriegfrj any thoughts?
