Changes all uses of notify_ghosts to use the real names of mobs (#90919)

## About The Pull Request

Quite simple - this changes every direct mention of a mob in a
`notify_ghosts` message to use `[mob.real_name]` instead of just `[mob]`

## Why It's Good For The Game

makes things less confusing - ghosts can see easily their actual
identity anyways, so it's not like there's much of a reason _not_ to do
this.

## Changelog
🆑
qol: Ghost notifications will now use the real names of mobs when
something happens (i.e no more "Unknown has completed an ascension
ritual!")
