Demonstrates Mcp.ReadResource, which calls the MCP resources/read method for a resource identified by URI and places the contents into a JsonObject.

Tip: Code to parse the returned JSON can be generated with Chilkat's online tool at https://tools.chilkat.io/jsonParse.

*  Connect to a public MCP (Model Context Protocol) server over its Streamable HTTP endpoint.  The

*  Read a specific resource by its URI.  A resource URI is obtained from the "resources" array
*  returned by ListResources.  The resource contents are placed in the JsonObject.
