Description
The HttpMethodsClient constructor allows to get an RequestFactory or RequestFactoryInterface as second parameter.

Both declare the createRequest but don't have the same argument.

RequestFactoryInterface::createRequest only have two parameters method and uri.

The HttpMethodsClient::send method which is used to make the HTTP call have two other parameters. So when using a PSR-17 implementation, the code will not work as the body and/or headers won't be sent.

How to reproduce

$http = new HttpMethodsClient(HttpClientDiscovery::find(), Psr17FactoryDiscovery::findRequestFactory());
$response = $http->get($uri, $headers);

Headers will not be sent.
