MINOR: Use Gradle's JUnitPlatform for upgrade-system-tests modules (#9922)

Add a runtime dependency on the jupiter engine to avoid failures
during `./gradlew unitTest/integrationTest/test` for `upgrade-system-tests-*`.

Also remove `connect` and `examples` from the JUnit 5 blocklist since they
contains no tests.
