Creates and returns a new client for interacting with the AWS Bedrock API for Anthropic models.

AWS credentials are resolved according to the AWS SDK's default resolution order, described at https://docs.aws.amazon.com/sdk-for-ruby/v3/developer-guide/setup-config.html#credchain or https://github.com/aws/aws-sdk-ruby?tab=readme-ov-file#configuration
