Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request modifies the stale image cleanup utility to prevent the accidental deletion of specific versioned prebuilt images. By updating the filter criteria, the script now preserves images tagged with the 2.*.0 version pattern in addition to the 'latest' tag.

Highlights

• Image Cleanup Filter Update: Updated the gcloud container image cleanup script to exclude versioned images matching the pattern 2.*.0 from being deleted.
