Modal: Old danger buttons still used

Steps to reproduce

Create a modal with a danger button

What is expected?

The documentation for nzOkType says "Button type of the OK button. Consistent with the type of the nz-button."
The button types in nz-button are primary, default, dashed, text, and link. To get a danger nz-button you should use the attribute nzDanger, so I expect to set something like

nzOkType="default"
nzOkDanger="true"

For nzFooter I expect something like

nzFooter: [
        {
          label: "Delete",
          type: "default",
          danger: true
          onClick: () => delete()
        }
      ]

What is actually happening?

I have to use nzOkType="danger" or type: "danger" as there is no property for nzOkDanger or configuration item for danger (There is a configuration item for ghost in nzFooter/ModalButtonOptions though)

This gives me primary danger buttons using the old class ant-btn-danger instead of the new ant-btn-primary ant-btn-dangerous
