Add Localization

🎌 Localization

We need to add localization on the website, adding many languages to come. The setup should be simple and for each language words/sentences should be in its own separate json file in an object, english included. Also we need to save the selected language value in local storage and auto loading it whenever the user comes back to the website. For the selector of the languages we need to have it in the footer for now, right or left side either works.

What we want to add for now:

• [ ] chinese
• [ ] greek
