Final content review

[gkwan-ibm]

• double check that the gRPC only support EE8 (using javax.* packages, and not jakarta.*)
• change the System.out code to use JUL
  • see the changes in https://github.com/OpenLiberty/draft-guide-jakarta-websocket/pull/13/files except from the README.adoc and index.html
• rename the methods in SystemService.java file
  • getPropertiesServer() to getServerStreamingProperties()
  • getPropertiesClient() to getClientStreamingProperties()
  • getPropertiesBidirect() to getBidirectProperties()
  • update the README accordingly

Addressed in #17

mvn -pl systemproto install generates class target/generated-sources/protobuf/grpc-java/io/openliberty/guides/systemproto/SystemServiceGrpc.java that contains javax.annotation.Generated. It is EE8 namespace.

Same issue in grpc/grpc-java#9153, and it may be related to grpc/grpc-java#9179

The solution for javax.annotation.Generated is to post process the generated code with https://openliberty.io/blog/2021/03/17/eclipse-transformer.html as the OpenLiberty FAT bucket does for EE9+ and it will be good for the guide to mention this @gkwan-ibm  ....Actually having reviewed how the FAT tests do this - it would not be easy for users to cut'n'paste the way we do it there, so just a reference to https://openliberty.io/blog/2021/03/17/eclipse-transformer.html is probably best
