[MIRROR] Gondolas are now basic mobs (#27934)

* Gondolas are now basic mobs (#83451)

## About The Pull Request

This PR turns gondolas into basic mobs and does some fiddling with
gondola pods
Their verbs are now action buttons which they lose upon delivering. If
set to stay, they won't have their abilities afterwards (or wont get
them in the first place if the delivery is already done).
Lets them survive without a pod requirement in case admins want to spawn
one for their own stuff, so I also removed it from the snowflake checks
to exclude them from stuff.

Also replaced the hardcoded "cant speak" with simply giving the mute
trait, so admins can make gondolas speak if they want to for any reason.

## Why It's Good For The Game

The pet level of simple animals can finally be killed off, also gives
admins more control over gondola-related stuff if they so wish.
