kogito-quarkus-test-list.xml file is not unique in Central

Recently we ended up with issues on 1.26 release because `kogito-quarkus-test-list.xml` is already existing with same content, due to uniqueness rule setup in Nexus JBoss staging  profile.

Release process is now moved to a different staging profile (kogito profile) which does not have this rule, to avoid to block releases. But we should correct this issue in the xml file.
In order to correct this, a simple addition of the version as a xml comment should be enough.

Example: <!-- 1.26.0.Final -->
