Pull request overview

Adds module support for Ubuntu 26.04 by updating the default OpenJDK selection logic and extending unit test coverage to validate the expected package/JAVA_HOME behavior across supported Ubuntu releases.

Changes:

• Updated Debian-family release-to-OpenJDK mapping to default Ubuntu 26.04 to OpenJDK 21.
• Added Ubuntu 26.04 to the module’s supported OS list in metadata.json.
• Expanded java class spec coverage for Ubuntu 18.04/20.04/22.04 (OpenJDK 11) and added explicit specs for Ubuntu 24.04 (OpenJDK 17) and 26.04 (OpenJDK 21).

The original PR #623 for this has been closed by the contributor, but they still are interested in the fix. They have suggested (via a Slack conversation) that we continue by using this PR for further changes that are required.

I will update this branch to pick up the latest changes and see if we can get acceptance tests running against 26.04.

The acceptance tests ran cleanly, but they are still not running against Ubuntu 26.04:
Ubuntu-26.04 no provisioner found

This requires the testing infra team to fix so we can provision the testing environment.
