Add Gymnasium performance improvement to Lunar Lander

[pseudo-rnd-thoughts]

Farama-Foundation/Gymnasium#235 found a significant performance improvement to Lunar Lander

Using benchmark_step, the gymnasium environment achieves ~15000 steps per second (on my laptop), while mo-gymnasium currently achieves ~6500.

from gymnasium.utils.performance import benchmark_step
import mo_gymnasium

env = mo_gymnasium.make("LunarLander-v2")
mo_env = mo_gymnasium.make("mo-lunar-lander-v2")

print('env benchmark', benchmark_step(env, target_duration=15))
print('mo-env benchmark', benchmark_step(mo_env, target_duration=15))

This update achieves ~8000 which is still significant performance difference, which should be investigated further

Amazing, that's why staying close to Gymnasium is so convenient. Thanks a lot Mark. Cheers,
