refactor(github): build GraphQL query without the client bundle

The eightpoints/guzzle-bundle and idci/graphql-client-bundle only
existed to build one near-static query string, and the bundle's own
HTTP transport was already bypassed in favor of Symfony HttpClient.
Build the query with sprintf/json_encode instead, drop both bundles
from config/bundles.php, and update the test double accordingly.
