📝 Summary

Summary by CodeRabbit

• Updates
  • The operator now defaults to Argo CD 3.5.4 and Image Updater 1.3.1. These updated versions are used when no custom image is specified, bringing their release updates to new and default-configured installations. Installations that explicitly select their own images continue using those selections. The default Argo CD image is also updated to match the new version.

Walkthrough

The operator’s Argo CD version changes from v3.5.2 to v3.5.4, and its Image Updater version changes from v1.3.0 to v1.3.1. The Go module replacements and image defaults are updated to match.
