Bedrock snowlog and cauldron for Java parity

With this drop theme, I think it's the best time to bring snowlog to java.

Other than that, Java needs cauldron parity. The way the cauldron works in Bedrock would allow players in Java to also gain access to tipped arrows without needing to collect the dragon breath, which shouldn't be locked behind encountering the dragons in the first place. It also gives more options for decoration.

I proposed that these two should be focused on this winter drop for parity.
