Private information doesnt expected at public docs

### Scribe version

4.40.0

### Your question

Name of tables or models doesnt expected at public docs.

If we have request like this:
```php
/**
* Query parameters.
*/
class SecureRequest extends FormRequest
{
public function rules(): array
{
return [
'request_key' => 'nullable|string|exists:'.SecureModel::class.',secure_column'
];
}

public function queryParameters(): array
{
return [
'request_key' => ['description' => 'Your access key'],
];
}
}
```

Scribe generate something like that:

> **request_key** string optional.
> Your access key. **The secure_column of an existing record in the App\Models\Secure table.**

but expected anoter result:

> **request_key** string optional.
> Your access key.
>

And now we cant disable this secure information.

### 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

Reproduce the issue with the shown SecureRequest FormRequest and inspect the generated API documentation for the request_key rule. Trace the Scribe documentation generation path that turns the exists rule into explanatory text; done means the user description remains while the table, model, and column details are omitted.
