Automatically deserialize as `TabularDataResource` when application/table-schema+json MIME type is shared

[jonsequitur]

Currently, the application/table-schema+json MIME type must be handled and deserialized by users in .NET kernels. This requires understanding of the type and some amount of manual plumbing code, even though the serialization settings and types are available in Microsoft.DotNet.Interactive.Formatting.

The .NET-based kernels should automatically deserialize this MIME type from JSON in a similar way to how it deserializes some other types (string, int, etc.)
