examples/facroty_demo build uses "cp" instead of "copy" on windows during "move model" task

When building the "factory_demo", the build script is using "cp" on windows instead of "copy" during the "move model" task.

Kindly remind: we have updated the new application firmware, which updates the speech recognition model, add features of continuous identification, the GUI interface is compatible with current two box series development boards. You can download and experience it. https://github.com/espressif/esp-box
