How to add new language?

Let's add the German language in the existing language.

1. Create a new file src/lang/gr.json

   {
     "Mega Menu": "Mega-Menü",
   }

2. Update the following code in src/routes/+layout.svelte.

   import { addMessages, init } from "svelte-i18n";
   
   init({
     fallbackLocale: "en", // use en if language is not found.
     initialLocale: "en", // replace "en" to "gr" to set the gr as default language.
   });

3. Now add the new option of German language in the topbar language dropdown menu src/common/data/languages.js

   {
     label: "German",
     flag: flaggerman,
     value: 'gr'
   }
