test and review following PR in image updater to support handling of force-update for zero-replica deployments:

https://github.com/argoproj-labs/argocd-image-updater/pull/1172 

This PR aims to fix the community-requested feature:

Update attempts when image is already up to date when no container exist
https://github.com/argoproj-labs/argocd-image-updater/issues/829
When there is 0 replica (e.g., in a cron job application), and force-update is true, image updater keeps updating the image even if the image is already up to date. This repeated updates should be avoided.
