Fully qualified property names not recognized in deserialization

[filip-kinsky]

Describe the bug

Property names can be fully qualified (prefixed with namespace) in Schema.org JSON the deserialization doesn't seem to work for that. I'm trying to use this library for Schema.org based API integration.

Steps to reproduce

Copy of part of data from the test https://github.com/RehanSaeed/Schema.NET/blob/main/Tests/Schema.NET.Test/Examples/RestaurantTest.cs#L63 with fully qualified property names in a test which fails:

        var json =
        """
        {
            "@context": "https://schema.org",
            "@type": "Restaurant",
            "@id": "https://davessteakhouse.example.com",
            "name": "Dave's Steak House",
            "https://schema.org/address": {
                "@type": "PostalAddress",
                "addressCountry": "US",
                "addressLocality": "New York",
                "addressRegion": "NY",
                "postalCode": "10019",
                "https://schema.org/streetAddress": "148 W 51st St"
            }
        }
        """;
        var restaurant = SchemaSerializer.DeserializeObject<Restaurant>(json)!;

        // following throws as restaurant.Address is not populated
        restaurant.Address.HasValue.ShouldBeTrue();
        restaurant.Address.OfType<PostalAddress>().Single().StreetAddress.Single().ShouldBe("148 W 51st St");

Expected behaviour

Deserialization should populate even properties with fully qualified names - this is valid according to Schema.org definition

Schema objects
