AMX-30 classifier

BUR #33692 has been rejected.

rename amx-30 -> amx-30_(tank)

We need a classifier for the AMX-30. I was searching it a few moments ago and noticed that we have AMX-30 AuF1 posts tagged as AMX-30. While they are based on the same chassis they are different vehicles and very visually different. Not sure if we want to alias because potentially users might throw AMX-30 in looking for the artillery piece and find the tank.

This bulk update request is pending automatic rejection in 5 days.

This can just be resolved by tagging the specific variant instead.
