Title: Updated curl flags in README.

The url redirects. Providing -L tells curl to follow the redirect.
-L, --location
(HTTP/HTTPS) If the server reports that the requested page has moved to a dif-
ferent location (indicated with a Location: header and a 3XX response code),
this option will make curl redo the request on the new place.
