LPS-34571 JavadocFormatter and Language.properties

Updated the formatter to copy the class desc from the ServiceImpl into Language.properties for respective *service-help properties. Some of the property values remain empty as their ServiceImpl javadoc is empty. So, I'll be sure to update those class descriptions.

Also, some of the {@link ...} stuff got copied in too. If they don't render properly, I can remove them. Thanks.
