refactor: Remove console.error from WriteFileTool

- Removes an unnecessary `console.error` call from the `shouldConfirmExecute` method in the `WriteFileTool` class.
- This logging was redundant as validation errors are already handled and returned by the method.
- Additionally, `console.error` is not suitable for this scenario, as incorrect arguments can be provided by the LLM, and these are anticipated and managed without needing an error log.
