Removed unnecessary workaround for pybind11's format_descriptor

#include <pybind11/operators.h>

namespace py = pybind11;

// including pybind11/numpy.h is needed for the specializations of py::format_descriptor

// for enum types, see https://github.com/pybind/pybind11/issues/2135

#include <pybind11/numpy.h>

#include "../tnl_indexing.h"

#include <TNL/Containers/Array.h>

// pybind11 should actually take care of this inside py::format_descriptor, but apparently it does not work...

// see https://github.com/pybind/pybind11/issues/2135
