refactor(models): simplify tools type annotation in ChatRequest

The type annotation for the `tools` field in the `ChatRequest` class was simplified from `List[ChatCompletionInputTool]` to `List`. This change reduces complexity while maintaining the same functionality, as the specific type within the list is not critical for the model's operation.
