Hi!

From https://github.com/openjournals/joss-reviews/issues/2791

I am still using Java 8 by default, but have up to Java 15 installed. When I tried java -jar ...jar, I got

$ java -jar v3xt.jar 
Exception in thread "main" java.lang.UnsupportedClassVersionError: uno/glfw/glfw has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Couldn't remember what was the 55 class file version, so randomly tried Java 11, and it worked. Checked the class file versions, it looks like that's Java 11, so I've added a section for the prerequisites (only Java for now).
