Issue: Issue: Generating documentation gives error:  "Zod type ZodDate is unsupported"
Whenever I try to generate OpenAPI spec using:

```
const yamlString = new OpenAPI({
  routing: routes, // the same routing and config that you use to start the server
  config,
  version: '1',
  title: 'Posterr API',
  serverUrl: 'https://localhost:8080'
}).getSpecAsYaml();
```

I get the following error:
```
Error: Zod type ZodDate is unsupported
