Add beekeeping village structure for minecraft plains village type

Adding a dedicated beekeeping structure to Plains villages would make the biome feel more alive while integrating existing bee mechanics naturally into village life.

Structure Design:
A small rustic cottage surrounded by a fenced-in flower garden containing 1-2 beehives, oak leaves, and a few campfires placed safely underneath the hives. Inside the house, players could find a chest with honeycombs, glass bottles, and flowers, alongside a Beehive or Honey Block centerpiece.

Gameplay Value:
- Early-Game Access: Gives players a reliable way to discover bees and learn how campfires pacify them during harvesting through environmental storytelling.
- Village Atmosphere: Bees flying between the garden and nearby village farm plots would naturally speed up crop growth, making the village feel like a working ecosystem.
- Optional Profession: The Beehive could even serve as a job site block for a new Beekeeper villager who trades emeralds for honey bottles, honeycomb, candles, and rare flowers.
