Use route prefix in baseUrl

### Scribe version

4.39.0

### Your question

If all the api route has `api` prefix, how can I set it in baseUrl?
For now when I set it in config `'base_url' => config('app.url').'/api',` the url generated will be `http://domain/api/api/login`

I'm using the openapi-ts tool for requests, and I don't want to fill in the same prefix every time

### Docs

- [x] I've checked [the docs](https://scribe.knuckles.wtf/laravel), the [troubleshooting guide](https://scribe.knuckles.wtf/laravel/troubleshooting), and [existing issues](https://github.com/knuckleswtf/scribe/issues?q=is%3Aissue+), but I didn't find a solution

Start with the Laravel documentation and the `base_url` configuration described in the issue, then inspect how Scribe builds URLs for the generated OpenAPI output used by openapi-ts. Done means configuring an API route prefix produces `http://domain/api/login`, without duplicating `/api` in the generated URL.
