Add DRF OpenAPI body parameters description
When creating a distribution one of the required body parameters is the publisher, as per DRF OpenAPI documentation.
/api/v3/distributions/ publisher string Required Publications created by this publisher are automaticallyserved as defined by this distribution
This parameter can not be any string, it has to be _href of the publisher, adding this to the description will improve the documentation. This is just one example, there are other similar cases.
