Fix the wishlist products sort dropdown under Bootstrap 5 themes

Description?	On the wishlist "products list" page the sort dropdown does not open — clicking it does nothing. The toggle button in ProductsListContainer.vue uses the Bootstrap 4 attribute data-toggle="dropdown". PrestaShop 9's default theme (Hummingbird) ships Bootstrap 5, which only recognises data-bs-toggle, so its dropdown plugin never binds to the button and the .dropdown-menu is never shown. This renames the attribute to data-bs-toggle="dropdown"; the rest of the markup (.dropdown, .dropdown-menu, aria-*) is already Bootstrap 5 compatible. The public/productslist.bundle.js is updated to match the source (the same single-attribute change the production build produces).

How to test?	With the Hummingbird theme (Bootstrap 5), add products to a wishlist, open the wishlist products list, and click the sort dropdown. Before: nothing happens. After: the dropdown opens and the sort options (Last added, price, etc.) are selectable. Root cause confirmed in the shipped bundle ("data-toggle":"dropdown" -> Bootstrap 5 ignores it); the fix makes the button carry data-bs-toggle so Bootstrap 5's dropdown plugin toggles the menu.
