Update Dependencies to Fix OpenAI API Parameter Error

[Jones0073]

Updates the versions of several dependencies in pyproject.toml—namely, langchain-community, langchain-openai, and both instances of langgraph—to address a dependency error that breaks reasoning models.

Issue Details:

• Error Encountered:
  During execution, an outdated call to the OpenAI API in the current versions of these libraries results in the following error:

  raise self._make_status_error_from_response(err.response) from None
  openai.BadRequestError: Error code: 400 - {'error': {'message': "Unsupported parameter: 'temperature' is not supported with this model.", 'type': 'invalid_request_error', 'param': 'temperature', 'code': 'unsupported_parameter'}}

• Root Cause:
  The libraries were using an API call that included a temperature parameter not supported by the model, leading to a BadRequestError.

Solution:

• Update Dependencies:
  The new versions of langchain-community, langchain-openai, and langgraph in the pyproject.toml implement updated API calls that remove the unsupported parameter and correctly interact with the OpenAI API.

Impact:

• Fixes:
  The update ensures that reasoning models can be used without encountering the OpenAI API error.
• Backward Compatibility:
  The changes should be backward compatible, as the updated dependencies maintain the intended functionality while fixing the error.
