Fix AWS Bedrock ARN parsing issue in converse methods (#544)

* Fix AWS Bedrock ARN parsing issue in converse methods

- Replace modelId.split('.') with parse_vendor_and_model_name_from_model_id
- Fixes crash when using ARN or cross-region model IDs with multiple dots
- Makes patch_converse and patch_converse_stream consistent with other methods

Resolves ValueError: too many values to unpack (expected 2) when using:
- ARN format: arn:aws:bedrock:us-east-1:<account_id>:inference-profile/us.anthropic.claude-3-haiku-20240307-v1:0
- Cross-region format: us.anthropic.claude-sonnet-4-20250514-v1:0
