A bundle recipe change + buff for rabbits

The change for the bundle recipe was a good one, as it became much more usable and easier to get. However, it reverted rabbit hide as an item back to its original redundant state. So the idea is simple: swap the leather in the recipe with rabbit hide, but, to make things fair, also buff rabbits a little bit to make them less unnecessarily tedious to find and kill. Perhaps, making their hitbox bigger would make them easier to aim at. Also some changes to their spawns or breeding mechanics, like making them spawn more frequently throughout all the other biomes (so far deserts, at the very least for me, were the only viable way of getting bundles) or even adding a chance of them having 2 or more children after breeding (could add a bit of realism and uniqueness to the mob).
