Translate "Home" link in site navigation

[hasantezcan]

We changed the structure a few days ago. #2312 Before the change, we could not translate the "Home" button for the other langs. But now every language can write their own word about the "Home" button. And now, let's translate it. I updated it for Turkish already. 😄
#2330

These languages need a translation;
bg, de, es, fr, id, it, ja, ko, pl, pt, ru, vi, zh_cn, zh_tw
