runtime(vimtutor): vimtutor throws Access Denied Error on MS-Windows

Problem:  MS-Windows: vimtutor throws Access Denied Error
Solution: switch the order of redirects. First redirect stdout, than
          stderr to stdout, Try to access $TEMP before current directory
          (which is usually c:\Program Files\vim\vim91\ and not writable
          for normal users)

closes: #17550
