* Makes the easter event spawning logic use a more curated list (#82275)
## About The Pull Request
The easter rabbit event looped through every single landmark in the
game, not checking for zlevel or purpose, just that they would not be
called "blobspawn". This PR makes the logic more curated, using generic
and maintenance event landmarks for normal bunnies, and carpspawn for
space rabbits.
Also added check_tick checks for a good measure.
There is a still a lot of them! I counted around 50 bunnies on average
per test.
## Why It's Good For The Game
A more curated list is better than a list that checks for name strings.
Ensures the rabbits spawn only on the station Z levels.
