[Doc] Update JPMS parameters for EAP8 GA

So far during EAP 8 GA work 2 new jpms parameters were identified

• --add-exports=jdk.naming.dns/com.sun.jndi.dns=ALL-UNNAMED
  https://issues.redhat.com/browse/WFLY-17127
  https://issues.redhat.com/browse/WFCORE-6087
• --add-opens=java.base/java.net=ALL-UNNAMED
  https://issues.redhat.com/browse/WFCORE-6346
  https://issues.redhat.com/browse/JBEAP-24837

We need to propagate this info to customers. As far as we know there exists just knowledge base article https://access.redhat.com/articles/6956861 informing about jpms parameters for EAP 74.

So I assume something similar needs to be created for EAP 8 GA if does not exit yet (did not find). This is major intent of this issue.

We did not find any link in documentation to this article. In our opinion t will be better if documentation at least link this knowledge base article, if that is documentation good practice. That would be nice to have output of this issue.
