FileUtil.copyFile()实际效果与注释不一致

[LeonemZhang]

版本情况

JDK版本： oraclejdk_8_202
hutool版本： 5.8.27（请确保最新尝试是否还有问题）

问题描述（包括截图）

方法注释说目的文件不存在会创建，但是实际运行的时候会报NoSuchFileException，显然是没有创建出目的文件

1. 复现代码

            URL url = new URL(fileUrl);
            URLConnection connection = url.openConnection();
            String fileName = url.getFile().substring(url.getFile().lastIndexOf('/') + 1);
            final File downloadFile = FileUtil.file(destFolderPath, fileName);
            try (InputStream inputStream = connection.getInputStream()) {
                log.info("开始下载文件：{}", fileUrl);
                FileUtil.copyFile(inputStream, downloadFile, StandardCopyOption.REPLACE_EXISTING);
                log.info("文件已下载到：{}", destFolderPath);
            }

确实存在这个问题。

问题在于：

1. 如果只是文件不存在，则不会报错
2. 如果文件所在目录不存在，则会报错。

5.8.28 修复此问题！
