Confirmation message for deletion does not pick up resource translation

[straurob]

What you were expecting:
When deleting an item I expect the confirmation message to pick up the translated resource name. In the below screenshot that would be Staat or Staaten.

What happened instead:
The confirmation message shows the untranslated resource name staat.

Steps to reproduce:

1. Setup translation messages (for the locale de) in i18n.js.
2. Provide a resource named staat (or any other name).
3. Open the list view.
4. Select one or more entries.
5. Click "Delete".

module.exports = {
  de: {
    resources: {
      staat: {
        name: "Staat |||| Staaten",
        fields: {
          // Fields go here...
        }
      }
    }
  }
}

Other information:
As far as I can see this seems to be related to BulkDeleteWithConfirmButton.js in the ra-ui-materialui package.
