The [Eliza repo](https://github.com/ai16z/eliza/tree/main/characters) uses an array of strings for knowledge instead of an object. Would it be worth updating the schema [here](https://github.com/ai16z/characterfile/blob/f6e51e23e849ab49c3180449006754ccd1ebe521/schema/character.schema.json#L81) in order to do validate Eliza character files?
