If the stderr output is not handled, then it needs to use RunWithStderr to make sure the git error message is included in the returned error. Otherwise, when the git command fails, the error log won't show useful information. Ref: * #39795 : no useful information in log messages * https://github.com/go-gitea/gitea/pull/40160#pullrequestreview-5752720866
