npm run send-introspection-query does not work.

$ npm run send-introspection-query http://localhost:3000/graphql
npm ERR! missing script: send-introspection-query

npm ERR! A complete log of this run can be found in:
npm ERR!     /Users/lallinuo/.npm/_logs/2019-04-22T07_09_52_599Z-debug.log```

it should be npx send-introspection-query http://localhost:3000/graphql instead.

And poof it's gone:

$ npx send-introspection-query http://localhost:3000/graphql

Maybe it's temporary?
