Moneropedia localization fix

I realized that since i did the moneropedia relocalization, the articles were not displaying the Moneropedia header and entry name sub-header.
To solve this, we need to merge this huge change that mainly handle the entry names in the language yml files.
I'm not fully satisfied, as the entry name should be handled in both the enty file itself and the yml, but reading the yml from the moneropedia.rb is perhaps a bit huge.

I think i will have to rewrite a portion of the readme after.
