fix: emit unknown output type when response has no JSON content

Operations with non-JSON responses (e.g. streaming, plain text) were
missing the Output type argument on Command, shifting Query into the
Output slot and Header into the Query slot. This caused type errors
in generated commands for specs like Docker Engine API.
