* Fix missing 'kind' property in AgentServer http-tests sample files

Co-authored-by: brandonh-msft <20270743+brandonh-msft@users.noreply.github.com>

* Fix SemanticKernelAgent.http to use correct method and message format

Co-authored-by: brandonh-msft <20270743+brandonh-msft@users.noreply.github.com>
