[Improvement] Remove from the log "Object 'Kind' is missing in 'null' file"

[cmoulliard]

Improvement

When a YAML file, part of a package (like helm values file) is processed, then the following error message could be logged

Apr 10 08:35:40 ERROR reconciling custom pkg controller=localbuild controllerGroup=idpbuilder.cnoe.io controllerKind=Localbuild name=quarkus name=quarkus reconcileID=f12409c6-f278-467b-ad97-ec054f0c1cef err=Object 'Kind' is missing in 'null' file=external-secrets/values.yaml pkgUrl=https://github.com/ch007m/my-idp-packages//external-secrets

idpbuilder should avoid to report such an error for non Kubernetes resources/manifests when parsing yaml files
