Non-recursive types for Group definition may be unhelpful

[t0yv0]

Consider this example from dashboard.md:

  widget {
    group_definition {
      layout_type = "ordered"
      title       = "Group Widget"

      widget {
        note_definition {
          content          = "cluster note widget"
          background_color = "pink"
          font_size        = "14"
          text_align       = "center"
          show_tick        = true
          tick_edge        = "left"
          tick_pos         = "50%"
        }
      }

      widget {
        alert_graph_definition {
          alert_id  = "123"
          viz_type  = "toplist"
          title     = "Alert Graph"
          live_span = "1h"
        }
      }
    }
  }

Expected behavior

Expect to group any kind of widget into a group_definition.

Current behavior

Generated types for the widget nested under the group_definition are different and cannot be used in a group_definition.

}

./dashboard_test.go:22:13: cannot use pinkNote() (type DashboardWidgetArgs) as type DashboardWidgetGroupDefinitionWidgetInput in slice literal:
	DashboardWidgetArgs does not implement DashboardWidgetGroupDefinitionWidgetInput (missing ToDashboardWidgetGroupDefinitionWidgetOutput method)
