Describe the bug

The Witherstorm gateways don't spawn during the Witherstorm fight, as the JSON files can't be parsed by Gateways to Eternity.

Steps to reproduce

1. Start the server or client.
2. Observe the logs (Failed parsing gateways file), and, optionally:
3. Summon the Witherstorm, and try progressing through the fight.

Expected behaviour

During startup, the Witherstorm gateway files should get parsed successfully. During the Witherstorm fight, the Witherstorm gateways should spawn.

Additional information

An example of the relevant exception can be found on line 5019 in my logs. There doesn't appear to be a readily available JSON schema for this version of the Gateways to Eternity mod, but judging by the error message and the line at which the exception is raised, the command rewards are missing a desc property.

And, sure enough, after adding a description to all the command rewards (example below), all gateway files get successfully parsed and the gateways show up in-game during the Witherstorm fight.

# kubejs/data/gateways/gateways/witherstorm_gate.json
    {
      "type": "command",
+     "desc": "any.string.here",
      "command": "execute as <summoner> run witherstormmod phase set @e[type=witherstormmod:wither_storm,limit=1,sort=nearest] 4"
    },

Probably related to #2848.
