[BUG] Generates List<<List<SomeGet$Response>> instead of List<SomeGet$Response>

[anasJasim]

Describe the bug
The code generation process for the OpenAPI Swagger Dart library is producing incorrect output. Instead of generating a response type of List<ItemsGet$Response>, the code generator is generating List<List<ItemsGet$Response>>.

Generated output
File: openapi.swagger.dart

abstract class Openapi extends ChopperService {
    @Get(path: '/items')
    Future<chopper.Response<List<ItemsGet$Response>>> _itemsGet(
        {@Query('tenantUnitId') required int? tenantUnitId});
}
// ...
typedef ItemsGet$Response = List<ItemsGet$Response$Item>;

Expected output
File: openapi.swagger.dart

abstract class Openapi extends ChopperService {
    @Get(path: '/items')
    Future<chopper.Response<ItemsGet$Response>> _itemsGet(
        {@Query('tenantUnitId') required int? tenantUnitId});
}
// ...
typedef ItemsGet$Response = List<ItemsGet$Response$Item>;
