Even Jug Increments for v1.21 & v1.22

Changes the increments of jugs from 0.3L at vanilla to 0.2L instead.

Original mod by ext_, updated for v1.21.5-7 and v1.22.0-.3. It may also work on earlier 1.21 versions (haven't tested) and it's incompatible for versions earlier than v1.21 (use the original mod for those earlier versions).

This mod can be removed at the original author's request.
