Add PUT request handling in InvokeRecActionCommandHandler

Implemented HTTP PUT request handling in the
InvokeRecActionCommandHandler class. Previously, the PUT case
only had a placeholder comment. Now, it uses
http.PutAsync to send a PUT request to the specified
action.EndpointUri, aligning it with the existing POST
request handling.
