create two ocirepo sources sylva-units and sylva-core
As discussed in this comment: !428 (comment 2926143990)
We don't provide today a single OCI artifact containing both sylvaunits helm chart and kustomize-units.
This MR dynamically creates an ociRepo source targeting kustomize-units artifact when creating the sylvaUnits ociRepo.
It's imply having two artifacts named sylva-units and kustomize-units or it will not work.
