      In the set_fireworks loot item function, the "mode" field is always required, even when it is only used to apply the optional "explosions" lists.

      How to reproduce

      1. Create a data pack with the following item modifier, I expect it to set the flight duration to 2 and keep the explosions the same
          "function": "set_fireworks",
          "flight_duration": 2
      2. The item modifier is invalid
      3. Add the "mode" field
          "function": "set_fireworks",
          "mode": "append",
          "flight_duration": 2
      4. This makes the item modifier valid again and it behaves as expected. (Internally it appends an empty list of explosions to the existing explosions)
