[MIRROR] Updates the wizard's den [MDB IGNORE] (#24373) (#134)

* Updates the wizard's den (#78723)

## About The Pull Request

I am the mapping demon, the mapping vampire, the mapping LICH. I am
going to suck the soul out of every single map in the game. I've sucked
the beach away mission's soul now I'm going for the wizard's den.

## Why It's Good For The Game

The wizard's den no longer looks like a giant flying cucumber, also it
looks a lot better and has a lot better themeing. The wizard also has a
book directing them to their wiki page to help them.
