chore(dependencies): update to latest node-sass

when I run script:
    npm install --save @ionic/app-scripts
the cmd log:
    https://github.com/sass/node-sass/releases/download/v4.5.0/win32-x64-57_binding.node 
    HTTP error 404 Not Found
And I see https://github.com/sass/node-sass/releases, v4.5.0/win32-x64-57 no longer exists!
So can I modify  node-sass version to work this out？
