Villagers ride Chickens

What this Datapack does

Lets you mount a Villager on a Chicken for easier Transportation.
Technically, this is a Vanilla feature, as there is a chance that a Chicken Jockeys spawns as a Baby Zombie Villager that, when cured stays mounted on the chicken.

Why?

A friend asked me to set up a server-side mod that allows villagers to be leashed, as they wanted to move them around more conveniently. After watching a video by Zedaph, I created this datapack to accomplish that task without a more resource-intensive mod or datapack while still staying kind of vanillaish.
