📝 fixed examples for Wandbox
As I learned in https://github.com/melpon/wandbox/issues/209, this
library is already installed at Wandbox, so we need to adjust the
examples to use `#include "json.hpp"` insteas of `#include <json.hpp>`.

{
// create a JSON object
json j_object = {{"one", 1}, {"two", 2}};
// call find
auto count_two = j_object.count("two");
auto count_three = j_object.count("three");
// print values
std::cout << "number of elements with key \"two\": " << count_two << '\n';
std::cout << "number of elements with key \"three\": " << count_three << '\n';
