"load_parents" as a query parameter for CreateMetaData

In the API doc https://arkindex.teklia.com/api-docs/#tag/elements/operation/CreateMetaData load_parents is present as a query parameter for the CreateMetaData endpoint; I guess it comes from this https://gitlab.com/teklia/arkindex/backend/-/merge_requests/1819 and makes sense as the CreateMetadData and ListElementMetaData endpoints are based on the same thing, but it's weird.
