[Quests] Integrate miro raids board directly into MetaOS

[peth-yursick]

What would you like to be added?

Right now, clicking "raids" takes people into the wiki page called "raids" which has a miro board integrated. Instead of doing this, the miro board should be integrated to open directly under the megamenu in full size. Also, there's a new miro board for season 7 (wiki page is still on season 4 or 5 😬)

Note: this would still be a temporary solution until #642 is completed. If you are able to do #642 instead, would probably be worth doing that.

Why is this needed?

Right now there's an unnecessary extra step which makes it load slower & look uglier. The UX could be significantly improved by implementing this simple change.
