Hono: zod output file is not defined.($ref schemas)

[manabu0926]

This plugin is very useful! Thanks for making it!
The following sample writing style works well.　(And without hono with zod is works well.)

https://github.com/orval-labs/orval/blob/master/samples/hono/hono-with-fetch-client/petstore.yaml

But Our project, splitted schema files like this.
openapi/
openapi/schemas/
openapi/paths/
openapi/openapi.yml

What are the steps to reproduce this issue?

1. Define splitted openapi.yml
2. command yarn orval
3. output file but, not define petstore.zod.ts

What happens?

1 define like this.
openapi/openapi.yml

orval.config.ts

import { defineConfig } from "orval";

export default defineConfig({

  backend: {
    input: {
      target: "./openapi/openapi.yml",
    },
    output: {
      mode: "split",
      client: "hono",
      schemas: "./hono/src/schemas",
      target: "./hono/src/index.ts",
      override: {
        hono: {
          handlers: "hono/src/handlers",
        },
      },
    },
  },
});

import { z as zod } from 'zod';

Hi @manabu0926 thanks for made this issue.
I understand that ref of OpenAPI is not resolved with zod.
Until the issue is resolved, use another tool to merge into a single OpenAPI definition and specify it as input.
