[MIRROR] Experimentor will no longer duplicate Bags of Holding [MDB I…

…GNORE] (#4438)

* Experimentor will no longer duplicate Bags of Holding (#84851)

## About The Pull Request

This feature of the experimentor is ~6 years old, back when BoHs didn't
need anomaly cores, but now that BoHs need anomaly cores this just
bypasses the anomaly core limit. And now it will not.

Closes #84849 

## Why It's Good For The Game

Limits to the amount of anomaly core items that can exist aren't
supposed to be able to be bypassed this easily.

## Changelog
