Description

We need documentation for the setup guide field being added to the create/edit rule forms and the corresponding setup field being added to the related API schemas. Right now, the setup field is a prebuilt rules only field - this change will allow the field to be used in custom rules as well by adding a markdown container to the create/edit rule ui forms and adding the setup fields to the create/update/patch rules api schema - not just the response schema.
