Subtitle for switching a copper golem's pose is incorrect

Right clicking a copper golem statue produces the subtitle “Copper Golem is petrified”, which is wrong: it’s already in a petrified state, we are just cycling through poses. I assume this is due to reuse of a sound event in a way that should not happen.

To fix: introduce a new sound event specifically for interacting with a copper golem statue - it can point to the same audio, but the translation string should be different.
