Get /organizations/{id} change the order for associated planters

The endpoint: GET /organizations/{id} will return links which includes `associated_planter` currently, this link is: ` /planters?organization_id=${organization.id}&limit=20&offset=0` we need to change it to ` associated_planters: `/organization_id=${organization.id}&limit=20&offset=0&order_by=about` so the planters that has `about` content (not empty) will be ordered on the top of the list.
