Icemoon cliffside bench area adjustments redux (tgstation#86494)

## About The Pull Request

This readds my other lost-to-wallening PR, tgstation#85964.


![image](https://github.com/user-attachments/assets/f379782a-46e4-4105-911a-92f28f007432)

I made some slightly bigger changes this time, opening up the area a bit
more so you don't have trees spawning surrounded by walls.
## Why It's Good For The Game

Tree in wall bad.
## Changelog
:cl: Rhials
fix: Modifies the mapping around the icebox cliffside, guaranteeing a
bit more openness.
