Frozen Zombie also drops Ice (block)

Currently there is no way to automate Ice producing, since the only way to obtain Ice in item form is to mine them manually with Silk Touch Items.
Makes Frozen Zombie drops Ice will allow players to build Mob Farms inside Ice Cave biome to produce Ice automatically.

Could also apply this change on Husk to drop Sand for large-scale sand producing (it's not my idea it's someone else's that's forgotten), which unlocks the posibility of TNT automating using husk farm, creeper farm, and crafters, which could (partially) solves the problem of TNT duping bug.
Not all of it though; Things like world eater (huge flying machines that blows up a whole area of terrain to make empty spaces for highly effecient mob farm) still need a way to eject primed TNT in a moveable way, which requires some other changes, like pushable block entity (which is bad idea), or new ideas like Dispenser Minecart?

Actually Dispenser Minecart is another idea, but come on, an good update must have its new contents to be connected between existed contents, also we already have the example of off-topic shelves in The Copper Age drop and we community absolutely loves it, so Dispenser Minecart in Winter-Themed drop wouldn't be that weird.
