BUG: Google drive 无法成功创建配置

创建google drive上传配置时，程序要求输入跳转网址所得代码
输入进tgbot后会提示为 **未知的下载链接，请重新检查**
因此无法成功授权google drive

希望能修复这个bug，感谢开发者

Start by reproducing the Google Drive upload-configuration flow in the Telegram bot and trace how the authorization code from the redirect URL is handled. Check why that input is reported as an unknown download link; done means a valid code authorizes Google Drive successfully and the upload configuration can be created.
