AppSync config example doesn't match TypeScript defs

[ffxsam]

Someone should probably update the example code for creating a client, so it matches the TypeScript types.

const client = new AWSAppSyncClient(
  {
    url: appSyncConfig.graphqlEndpoint,
    region: appSyncConfig.region,
    auth: {
      type: appSyncConfig.authenticationType,
      apiKey: () => appSyncConfig.apiKey,
    },
  }
);

And in the AWS Console, when you download the AppSync.js file, it should definitely use the auth type enum:

import { AUTH_TYPE } from 'aws-appsync/lib/link/auth-link';

export default {
  graphqlEndpoint: 'https://xx',
  region: 'us-east-1',
  authenticationType: AUTH_TYPE.AWS_IAM,
  apiKey: 'xx',
};
