Some changes to the terms

Hey everyone! It's Thyaeria here, and I'll be announcing some changes.

Core official/figure -> Vice Premier/Vice Premier Xiao
- The 'core official/figure' in the Russia Arc will be changed to Vice Premier Xiao. It sounded really awkward for a long time for someone to be named 'core figure' for a long time now, so I actually did a reference to the old releases (Before the huge censorship wave took place) and found out that the core official/figure was initially a Vice Premier.

Three Flavour Cosmetics International -> Three Flavour International
- Perhaps some of you may have noticed that I'd changed the term silently without any announcement, but I figured that I should add it in here.
