Only 2xx mock responses are generated

[huwshimi]

What are the steps to reproduce this issue?

1. Create an openapi spec with 400 or 500 responses e.g.

openapi: '3.0.0'
info:
  version: 1.0.0
  title: Swagger Petstore
  license:
    name: MIT
servers:
  - url: http://petstore.swagger.io/v1
paths:
  /pets:
    get:
      summary: List all pets
      operationId: listPets
      tags:
        - pets
      parameters:
        - name: limit
          in: query
          description: How many items to return at one time (max 100)
          required: false
          schema:
            type: string
      responses:
        '200':
          description: A paged array of pets
          headers:
            x-next:
              description: A link to the next page of responses
              schema:
                type: string
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Labradoodle'
        '201':
          description: A paged array of pets
          headers:
            x-next:
              description: A link to the next page of responses
              schema:
                type: string
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Dachshund'
        '400':
          description: A paged array of pets
          headers:
            x-next:
              description: A link to the next page of responses
              schema:
                type: string
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Cat'
        default:
          description: unexpected error
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Error'
components:
  schemas:
    Labradoodle:
      type: object
      required: ['cuteness']
      properties:
        cuteness:
          type: integer
    Dachshund:
      type: object
      required: ['length']
      properties:
        length:
          type: integer
    Cat:
      type: object
      required: ['type']
      properties:
        petsRequested:
          type: integer
        type:
          type: string
          enum:
            - cat
    Error:
      type: object
      required:
        - code
        - message
      properties:
        code:
          type: integer
          format: int32
        message:
          type: string

3. Generate mocks using orval

What happens?

Orval only generates an http response with a 200 status (which picks from an array of all 2xx so these can't be used independently) and does not generate any code for error responses:

export const getListPetsMock = () =>
  faker.helpers.arrayElement([
    { cuteness: faker.number.int({ min: undefined, max: undefined }) },
    { length: faker.number.int({ min: undefined, max: undefined }) },
  ]);

export const getSwaggerPetstoreMSW = () => [
  http.get("*/pets", async () => {
    await delay(1000);
    return new HttpResponse(JSON.stringify(getListPetsMock()), {
      status: 200,
      headers: {
        "Content-Type": "application/json",
      },
    });
  }),
];

What were you expecting to happen?

Mocks for all responses to be generated so that each response can be tested.

Any logs, error output, etc?
