GraphQL result to query gives a wrong result for a required parameters of `Create Check Run`

# Context
Octokit documentation on how to create a Check Run is missing 2 required properties: `name` and `head_sha`. Detailed explanation in Octokit: https://github.com/octokit/plugin-rest-endpoint-methods.js/issues/441

# Where could be the problem?
GitHub's Open API information (the dereferenced one) and Octokit's API dereferenced look good. `name` and `head_sha` are there and are marked as `required`.

Instead of appearing those properties, the result of the query provides a property with `*` as key.

In a quick look of the code I see suspicious the following lines:
https://github.com/gr2m/github-openapi-graphql-query/blob/405891d8cd001f2c126174e6f1bf5f9847213a54/lib/schema-to-parameters.js#L3

and

But I'm not sure if that could be the issue. Any ideas to start digging a bit @gr2m ? :)
