[MIRROR] Removes language encryption keys [MDB IGNORE] (#22170)

* Removes language encryption keys (#76309)

## About The Pull Request

We want languages to be special to species, these devalue that and make
them far too common.
The listen only thing does this especially badly. I'm sorry arcane I
know it's good for cargo but this vibes horrible and we shouldn't have
it

## Why It's Good For The Game

You should be able to talk privately via language with minimal snoopage

## Changelog
🆑
del: Removed language encryption keys from cargo, s bad for species
talking among each other, a thing we want them to do
/🆑

* Removes language encryption keys

* Removes our own translation keys too.
