Add multi-language option in Prestashop Tawk.to module

Hi there,

I have a prestashop store in two languages, the thing with prestashop platform is that you cannot paste the tawk.to script code in all the pages depending if you want the chat in a specific language or in another, because there are hundred of page combinations.

So the chat will always appears in the same language no matter if you are in the english, spanish or french version of your site. And it can make your clients confused.
