Code Review

This pull request updates the recommended Trivy version in the scan-images.sh script to v0.69.2. The change is correct and aligns with the reasons outlined in the description. I have provided one suggestion to improve the robustness of the script by enhancing the check for Trivy's installation. This will provide a better user experience by failing early with a clear error message if Trivy is not available.

The current check for trivy can be improved for robustness and better user experience.

• If trivy is installed, trivy --version prints its output to stdout, which can be noisy.
• If trivy is not installed, the script prints a message but continues, failing later on. This can be confusing for the user.
• Diagnostic messages should be printed to stderr, not stdout.

The suggested change addresses these points by silencing the version check, exiting immediately if trivy is not found, and printing messages to stderr.
