fix(v2PipelineTemplates): set response code to 200 OK because of swag…

…ger (#1307)

Swagger on 2.14.5 codegen for Go doesn't parse the body for a caller. The workaround for now is to return a 200 so swagger will return the body back to a calling method. This is documented in swagger-api/swagger-codegen#10435
