fix(webpack): Remove publicPath from output
fix(webpack): Remove publicPath from output

This fix is required to host this project on GitHub Pages.
If publicPath is '/', webpack generates an index.html which
has a script tag with '/bundle.js' src. This send a request to
'github.io/bundle.js' instead of 'github.io/web-keyboard-simulator/bundle.js'.
