Add support for AWS bedrock claude3 opus model support

Comment From: tzolov

@wmz7year , can you point me to a reference suggesting that AWS bedrock already supports Anthropic Claude3 Opus ? and for which reason?

According to the AWS docs only Sonnet and Haiku are supported: https://us-east-1.console.aws.amazon.com/bedrock/home?region=us-east-1#/providers?model=anthropic.claude-3-sonnet-20240229-v1:0

@tzolov Check this out: https://aws.amazon.com/about-aws/whats-new/2024/04/anthropics-claude-3-opus-amazon-bedrock/

But currently, it's only available in the US West (Oregon) AWS Region.
