Description

This PR fixes the map size error in MiniHack-MultiRoom environments where maps were being generated with dimensions exceeding the maximum allowed size (76x21)

Changes Made

• Modified map generation parameters to ensure dimensions stay within the maximum allowed size
• Updated docs to point to Farama MiniGrid
• Moved wizkit_items to options (how it is currently handled in nle)

Testing

• Verified environment creation works with MiniHack-MultiRoom-N6-v0

import minihack
import gymnasium as gym
env = gym.make("MiniHack-MultiRoom-N10-Lava-OpenDoor-v0")
env.reset()
env.render()

Closes #5
