Added find for kustomization.yml in AVP Kustomize

[eneamarcantoni99]

Description

Fixes: The PR fix the find in AVP Kustomize that not work if you use kustomization.yml instead of kustomization.yaml. I've added an OR in the find command so the plugin now works also with kustomization.yml (that is officially supported from kustomize command).
