Use multi-agent V1 for Amazon Bedrock models (#39804)

Browse Source 
## Why

Amazon Bedrock does not support the response items required by multi-agent V2.

## What changed

- Normalize Bedrock model catalogs to advertise `MultiAgentVersion::V1`.
- Cover both remote catalog normalization and the static Bedrock Runtime catalog in tests.
