Remove Extra Attack to Boar and Deer for Goths

The bonus was alright before Goths got free loom but there's no way to stop goths from sending a villager forward minute 2 and killing both your boar when they have loom and more attack against huntables. Its barely even a significant bonus outside the context of laming the opponents starting resources. With how fast they kill the opponent's boar the opponent can't stop it or even detect it in time. This way, they'll at least be able to stop it if they notice it.
