Moved the tramstation xeno egg into the middle of the chamber (#92332)

## About The Pull Request

See title

Fixes #92308 

## Why It's Good For The Game

Apparently people are failing to spot the egg hiding at the back of the
chamber, moving it into the middle gives it a better chance of being
seen. It also just looks neater in the middle.

## Changelog
🆑
map: Tramstation's xenobiology now receives xeno eggs in the middle of
the chamber instead of tucked away at the back.
