windeployqt can not find qtpaths executable

The windeployqt tool expects qtpaths to be installed, however the executable is actually called qtpaths6, so during the build, windeployqt fails to find qtpaths.

This happens due to the command (specifically, the `–qtpaths` option) that is generated by `qt_generate_deploy_app_script()`:

'C:/msys64/mingw64/bin/windeployqt-qt6.exe' 'C:/msys64/home/user/dev/draft/build/Draft.exe' '--dir' '.' '--libdir' '.' '--plugindir' 'plugins' '--force' '--qtpaths' 'C:/msys64/mingw64/bin/qtpaths.exe'
