Update rabbitmq docs examples to latest supported version (4.2.4)

[tamalsaha]

Bumps the rabbitmq example and guide manifests to the latest supported version (4.2.4) per the installer active_versions.json.

• General "deploy a rabbitmq" examples use the latest version.
• Version-upgrade guides keep a nearest-older source and upgrade to the latest (preserved as a real upgrade, not a no-op).
• Illustrative command outputs (kubectl get ...version tables, describe dumps) and other products'/backend versions are left unchanged.

Fix inconsistent Target Version in describe output.

The kubectl describe output shows Target Version: 4.4.26 but the RabbitMQOpsRequest CR sets targetVersion: 4.2.4. Update the describe output to match the actual target version.
