AIContext History - History API AdditionalContext should be under extras

Need to check if this is a severe breaking change or not.

The additionalContext param should've fallen under extras not the top level nodes object

query {
  aiMessages(requestIds: ["46b1fc10-262a-4fac-8fba-5b56fbdc886f"]) {
		nodes {
      content,
      extras {
        hasFeedback,
        sources,
        additionalContext... <--- should've been here
      },
      additionalContext {
        category,
        id,
        metadata,
      }
    }
  }
}
