    gnu: Add java-gson-2.8.6.
    
    This introduces a new package rather than upgrading the exist java-gson
    package because it is built using OpenJDK11; I didn't want to have to
    propagate that JDK dependency to the other packages that use it.
    
    OpenJDK 11 was chosen becuase this dependency was introduced for
    tla2tools.
    
    * gnu/packages/java.scm (java-gson-2.8.6): New variable.
