Bump to 1.93.0

Minecraft propagates "strong" redstone signals (such as those directly
from comparators or repeaters) through solid blocks. This includes
computers, which is a little annoying as it means one cannot feed
redstone wire from one side and a repeater from another.

This changes computers to not propagate strong redstone signals, in the
same way transparent blocks like glass do.

Closes #548.
