CI: JRuby test suite fails to compile

[olleolleolle]

This is a sign-post issue. jruby-head does not currently build right.

The setup-ruby step say this:

Modifying JAVA_HOME for JRuby
  attempting to run with existing JAVA_HOME
  /usr/lib/jvm/temurin-17-jdk-amd64/bin/java -jar /home/runner/.rubies/jruby-head/lib/jruby.jar --version
  Error: LinkageError occurred while loading main class org.jruby.Main
  	java.lang.UnsupportedClassVersionError: org/jruby/Main has been compiled by a more recent version of the Java Runtime (class file version 65.0), this version of the Java Runtime only recognizes class file versions up to 61.0
