Update to GraphQL-JS v14

[MichalLytek]

Hi @ivome!

I've tried to update graphql-query-complexity to support graphql-js v14 but I got this error while running the tests:

(...)
\graphql-query-complexity\node_modules\graphql\validation\validate.js:89
    throw new Error(errors.map(function (error) {
          ^
Error: Unknown directive "complexity".

Unknown directive "complexity".

Unknown directive "cost".

Unknown directive "complexity".

Unknown directive "complexity".

Because v14 is making better validation of the schema/query:
https://github.com/graphql/graphql-js/releases/tag/v14.0.0

Can you take a look at your test suite and maybe update readme to add info about the demand of registering directives explicitly? 😕

Just upgraded the library to support graphql-js v14. New version is published on NPM

Thanks! 🎉
You could just add || ^0.14.0 to not making a breaking change as it's doesn't seem to be needed.

Done! 😉
