Documentation update

In https://developer.garmin.com/connect-iq/api-docs/Toybox/Communications.html#makeWebRequest-instance_function you do the following:

   function makeRequest() {
       var url = "https://www.garmin.com";                         // set the url

       var params = {                                              // set the parameters
              "definedParams" => "123456789abcdefg"
       };

       var options = {                                             // set the options
           :method => Communications.HTTP_REQUEST_METHOD_GET,      // set HTTP method
           :headers => {                                           // set headers
                   "Content-Type" => Communications.REQUEST_CONTENT_TYPE_URL_ENCODED},
                                                                   // set response type
           :responseType => Communications.HTTP_RESPONSE_CONTENT_TYPE_URL_ENCODED
       };

       var responseCallback = method(:onReceive);                  // set responseCallback to
                                                                   // onReceive() method
       // Make the Communications.makeWebRequest() call
       Communications.makeWebRequest(url, params, options, method(:onReceive));
  }
  

The example code has a "bug", it doesn't make use of the just create responseCallback var.

       var responseCallback = method(:onReceive);                  // set responseCallback to
                                                                   // onReceive() method
       // Make the Communications.makeWebRequest() call
       Communications.makeWebRequest(url, params, options, method(:onReceive));
       // Change to
       Communications.makeWebRequest(url, params, options, responseCallBack);
