No enum constant org.bukkit.Material.GRASS

[Bloodlex]

Hey, could you please help making this awesome plugin work on 1.20.6? :) Thank you very much!

I've created a fork, because I couldn't push a branch to your repository here: #3

You can check the changes, I've updated some dependencies and make it work with experimental 1.20.6 API.

I've also discovered that GRASS is no longer a material and changed it in my configuration accordingly.
