Don't define hreflang language by shop language

[Chrisi1321]

Hi Guys,

Great module and works almost like it should.

I have a multishop configuration with a shop for Germany one for Austria and one for switzerland.
Language is always the same (german).

As it is not possible in Prestashop 1.7 to add a second / third language with the same iso code the module has a problem to set the correct language code for the stores.

   
 <link rel="alternate" hreflang="x-default" href="https://www.aktiv-naturheilmittel.at" />   <link rel="alternate" hreflang="de-de" href="https://www.aktiv-naturheilmittel.at" />   <link rel="alternate" hreflang="de-de" href="https://www.aktiv-naturheilmittel.de" />   <link rel="alternate" hreflang="de-de" href="https://www.aktiv-naturheilmittel.ch" />   <link rel="canonical" href="https://www.aktiv-naturheilmittel.at" />

As you can see the correct hreflang setup should have de-at for Austria and de-ch for Switzerland.

In backoffice there is the possibility to set the correct paramaters for each store, so perhaps it possible to for to change the variables in the code.

Would be great,
Thanks
