AmazonBedrock Generator: no IDs in meta anymore in 2.0

[lambda-science]

Describe the bug
2.0 Implementation of Amazon Bedrock Cat Generator removed the "ids" for the metadata of a replies from a generator. This was important for my app, is that something forgotten during implementation of the converse API or a change in Amazon own API (anwer)?

Before (<2.0):

        "meta": {
          "id": "msg_bdrk_018ZjKrcZ586g92r7dmLkCGx",
          "stop_sequence": null,
          "model": "claude-3-haiku-20240307",
          "usage": {
            "prompt_tokens": 12618,
            "completion_tokens": 231
          },
          "index": null,
          "finish_reason": null
        }

After (>=2.0):

        "meta": {
          "model": "anthropic.claude-3-haiku-20240307-v1:0",
          "index": 0,
          "finish_reason": "end_turn",
          "usage": {
            "prompt_tokens": 6026,
            "completion_tokens": 280,
            "total_tokens": 6306
          }
