readme: remove deprecated --save npm install option #4

Closed olets closed 5 years ago

olets commented 5 years ago

npm install no longer has a --save option (the equivalent is now --save-prod), and the --save/--save-prod behavior (adding installed packages to the package.json dependencies) has been the npm install default since npm v5.0.0. So no flag is needed.

This PR removes --save from the suggested npm installation command
