Fix the issue with error message logging for the check-attr command on Windows OS. (go-gitea#34035)

Close go-gitea#34022 , go-gitea#33550 

This error message always appears when using the `check-attr` command,
even though it works correctly.
The issue occurs when the stdin writer is closed, so I added a special
case to handle and check the error message when the exit code is 1.
