Now that we're documenting, and properly validating, the x-koha-embed parameter we can actually use this parameter definition list instead of the custom x-koha-embed array from the top level of the endpoint definition. This would reduce overhead of adding embeds.. we would only need to add them to the enum list in the parameter definition instead of to both the parameter definition and a top level x-koha-embed key.
