[FIX] website_sale: make search bar suggestions visible

Since 13.2, the cards cannot contain an overflowing element anymore as
we needed to enforce 'overflow: hidden' for the border-radius option.

Note: this commit adds data-vxml="001" on the snippet. This will allow
users which have already added the card version of the snippet in their
website to receive a notification that the snippet is deprecated once we
will have implemented that system (in progress).
