Gets rid of mobile hollow bioscramblers spawning in the anomaly research ruin. (#89303)

## About The Pull Request

What it says on the tin. Mobile anomalies still spawn in and around the
ruin, but never bioscramblers.

## Why It's Good For The Game

A) These fucking things cannot be disabled by conventional means. It
needs anomaly research.

B) They drift through space away from the ruin literally every single
time the ruin spawns. They are meant to be an environmental hazard for
the ruin, not for the entire playing space because a remote ruin
spawned.

C) Because they are not blocked by walls, they will keep drifting until
eventually arriving on the station, where they will stay there.
Typically occupying a space perpetually until a scientist comes and
fixes the problem with their anomaly neutralizer.

The only reason this happened was because of bioscramblers being
reworked into the state they are now. I don't imagine the original
creator intended for the ruin to create problems for the wider round
like this.

## Changelog
🆑
del: Mobile hollow bioscramblers no longer spawn from the anomaly
research ruin, sparing everyone from the inevitable unannounced arrival
of a permanent hollow bioscrambler aboard the station. You maybe still
encounter immobile bioscramblers in the ruin, however.
