In the [Hugo documentation](https://gohugo.io/content-management/multilingual/#use-translation-tables) it explains using translation tables as a possible way of localizing menu entries. This basically uses the menu identifier as a language key for the name of the entry, and is present in the [example menu template](https://gohugo.io/templates/menu-templates/#example). This change basically gives the same functionality to PaperMod.
