ccurme 32fcc97a90 openai[patch]: compat with Bedrock Converse (#31280)
ChatBedrockConverse passes through reasoning content blocks in [Bedrock
Converse
format](https://docs.aws.amazon.com/bedrock/latest/APIReference/API_runtime_ContentBlock.html).

Similar to how we handle Anthropic thinking blocks, here we ensure these
are filtered out of OpenAI request payloads.

Resolves https://github.com/langchain-ai/langchain/issues/31279.
