Add Java version - see guardian/gha-scala-library-release-workflow#36

Although we're _building_ with Java 21, we're also updating the minimum supported Java version from Java 8 to Java 11: #442 (review) We can do this because the artifact published by this repo: "com.gu" %% "janus-config-tools" % "1.0.0" https://index.scala-lang.org/guardian/janus-app/artifacts/janus-config-tools ...is only consumed by these two apps, Janus & Security HQ: * guardian/janus#3947 * guardian/security-hq#413 ....both of which are now running on Java 11.
