Add workflow generator option for installing Java

[mbg]

Gradle 9 is now the default version of Gradle on the GHA runners. This seems to cause failures because JDK 8 is the default and Gradle 9 requires JDK 17.

This PR adds a new installJava option to the sync.py script which behaves exactly the same as installGo, except for setup-java.

I have added installJava: "true" to the two workflows we have seen fail.

Pull Request Overview

This PR adds Java installation capability to the workflow generator to address Gradle 9 compatibility issues with JDK 8. The new installJava option allows workflows to automatically install JDK 17, which is required for Gradle 9.

• Adds installJava configuration option to the sync.py script that mirrors the existing installGo functionality
• Enables Java 17 installation for two autobuild direct tracing workflows that were failing with Gradle 9
• Generates workflow inputs and setup-java action steps when installJava: "true" is specified
