Enables the Update 1.21 experimental features, but disables the trial chambers and breeze. Notably, in 1.20.5+ the new raid mechanics will also be enabled, with pillagers dropping ominous bottles instead of giving bad omen.

3. Enable the "Update 1.21" feature flag `level.dat`. A simple way to do this is by installing the [NBT Viewer](https://marketplace.visualstudio.com/items?itemName=Misodee.vscode-nbt) extension for [VSCode](https://code.visualstudio.com/)

4. Open the `level.dat` file in VSCode by dragging the file from the file explorer to the VSCode window
5. Inside `Data`, add a new list tag called `enabled_features`
