Steps to Test or Reproduce

1. Update orval.config.js with the OpenAPI spec and client configuration.
2. Ensure the oneOf schema definitions generate the correct constants for validation rules.
3. Verify that the generated constants match the values specified in the OpenAPI schema.

// orval.config.js
import { defineConfig } from "orval";

export default defineConfig({
  petstore: {
    input: "./petstore.yaml",
    output: {
      client: "zod",
      target: "./src/generated/zod.ts",
      override: {},
    },
  },
});

// petstore.yaml
