Subject: [PATCH] Build: Set default Java version for jenv users (#3651)

Project requires Java 8 for full build.
Certain modules are not getting compiled when Gradle is run with JDK 11.

For example, in jmh.gradle there currently is:

    if (jdkVersion == '8' && sparkVersions.contains("2.4")) {
      jmhProjects.add(project(":iceberg-spark:iceberg-spark2"))
    }

Provide explicit default configuration for those using `jenv` to manage
multiple JDKs, to help contributors build the project.
