Can't fetch schema.org data if it contains "@graph"

[mercxry]

Hello, some websites use a slightly different version of schema.org that places all of the objects under a '@graph' tag, preventing the crate from fetching those tags because it expects them to be in the root object.

I can open a PR to fix this, let me know if you have any doubts or concerns!

      },
      {
        "@context": "https://schema.org",

        "publisher": {

            "url": "https://vice-web-statics-cdn.vice.com/images/vice-og.png"
          }
        }
      },
      {
        "@context": "https://schema.org",
        "@type": "ItemList",
        "name": "NYC Bans Students and Teachers from Using ChatGPT",
        "itemListElement": []
      },
      []
    ]
  }

the resulting html object:

HTML {
    title: Some(
        "NYC Bans Students and Teachers from Using ChatGPT",
    ),
    description: Some(
        "The machine learning chatbot is inaccessible on school networks and devices, due to \"concerns about negative impacts on student learning,\" a spokesperson said.",
    ),
    url: Some(
        "https://www.vice.com/en/article/y3p9jx/nyc-bans-students-and-teachers-from-using-chatgpt",
    ),
    ...
    schema_org: [],
}

In this case the schema_org field is empty, but I'm expecting the schema_org field to contain the objects under @graph.
