Feature proposal. Generate a type: union of literal numbers for response status codes

[o-alexandrov]

As the title says, how about generating a type for the response status codes?

• the type could then be used on the frontend/backend for type checking of the returned status codes

// example schema
import type * as OA3 from "openapi-ts"

const operationObject: OA3.OperationObject = {
  ...,
  responses: {
    200: { ... },
    401: { ... }
  }
}

And the generated type would be:

type statusCodes = 200 | 401
