Fix doubly-nested anchor tags

Build was printing:

  Warning: validateDOMNesting(...): <a> cannot appear as a descendant of
  <a>. See Marked > a > ... > a.

Caused by markup like:

  [https://example.com/](https://example.com)

Just rely on autolinking instead.

 Since a GraphQL API has more underlying structure than a REST API, there are more powerful clients like [Relay](https://facebook.github.io/relay/) which can automatically handle batching, caching, and other features. But you don't need a complex client to call a GraphQL server. With `express-graphql`, you can just send an HTTP POST request to the endpoint you mounted your GraphQL server on, passing the GraphQL query as the `query` field in a JSON payload.

 This way of defining object types often provides advantages over a traditional REST API. Instead of doing one API request to get basic information about an object, and then multiple subsequent API requests to find out more information about that object, you can get all of that information in one API request. That saves bandwidth, makes your app run faster, and simplifies your client-side logic.

 When you're passing arguments in code, it's generally better to avoid constructing the whole query string yourself. Instead, you can use `$` syntax to define variables in your query, and pass the variables as a separate map.
