Exposed, weathered and oxidized variants of copper golem statues do not use copper golem statue sounds

exposed, weathered and oxidized variants of copper golem statues do not use the same sounds that regular copper golem statues use, nor have their own unique sounds. instead, they use base copper block sounds.

Steps to reproduce:

1. ensure your sounds are turned up and carefully listen during the following steps

2. place and break a regular copper golem statue several times

3. place and break an exposed/weathered/oxidized copper golem statue several times

Observed result:

The regular copper golem statue uses unique sounds, while the other ones use the same sounds copper blocks do.

Expected result:

The other copper golem statue variants would use the same sounds as the regular copper golem statue, or have their own unique sounds.
