Update instructions for running the CLI

[cmungall]

It would be great if there were more instructions on how to run the CLI, and if these could be updated

In order to run on java 17, I had to add --add-opens java.base/java.lang=ALL-UNNAMED

e.g.

java --add-opens java.base/java.lang=ALL-UNNAMED -jar tools/logmap-matcher-standalone-july-2021/logmap-matcher-4.0.jar

Hi Chris, Many thanks! I think I'm a bit old-fashioned wrt Java... I will update the instructions!
