Removes actually concerning religious references (#76228)

## About The Pull Request
Someone said something stupid in a comment so I'm removing it

## Why It's Good For The Game
Not every religious reference is concerning, but the "allahu ackbar"
meme died out in the 2010s and was always kind of racist.

## Changelog
Doesn't need one.
