[FIX] website_sale: remove cart popover on language selectors in header

Since commit [1], when we are in the `/shop/cart` page and if a language
selector is in the header, a cart popover also appears when hovering the
languages. This happens because the `websiteSaleCartLink` widget
selector also targets the cart links inside the language buttons.

This commit solves this issue by excluding the language selectors from
this widget selector.
