tests: fix sortdict doctest with Python 3.12

The output of OrderedDict changed to use plain dict syntax:

  $ python3.11 -c "import collections;print(collections.OrderedDict([('a', 0), ('b', 1)]))"
  OrderedDict([('a', 0), ('b', 1)])

  $ python3.12 -c "import collections;print(collections.OrderedDict([('a', 0), ('b', 1)]))"
  OrderedDict({'a': 0, 'b': 1})
