Use correct getCommands() method

```yml
    1:
      DisplayName: '<red>Porkchop'
      DisplayItem: 'PORKCHOP'
      DisplayAmount: 4
      Chance: 60
```

If you simply want to give basic items without the need for using `Items:` or `Commands:`, You can configure a prize like this and it will give 4 porkchop.

DisplayAmount defines how many items to give, DisplayItem defines the material to give to the player.
