openai[patch]: Fix langchain-openai unknown parameter error with gpt-4-turbo (#20271)
**Description:** 

I fixed langchain-openai unknown parameter error with gpt-4-turbo.

It seems that the behavior of the Chat Completions API implicitly
changed when using the latest gpt-4-turbo model, differing from previous
models. It now appears to reject parameters that are not listed in the
[API
Reference](https://platform.openai.com/docs/api-reference/chat/create).
So I found some errors and fixed them.

**Issue:** https://github.com/langchain-ai/langchain/issues/20264

**Dependencies:** none
