drive: fixed the issue where Google Docs file name was truncated, causing panic or unparseable characters

When downloading Google documents, the remote does not contain the suffix, and the extension is '.docx'. The code here will cause panic or the file name will be truncated (if the file name is Chinese or Japanese, there will be unparseable characters)
