mgr/PyModule: use Py_ssize_t for the PyList index

also silences the warnings like:

mgr/PyModule.cc:574:30: warning: comparison of integer expressions of different signedness: 'unsigned int' and 'Py_ssize_t' {aka 'int'} [-Wsign-compare]
  574 |       for (unsigned i = 0; i < PyList_Size(p); ++i) {
      |                            ~~^~~~~~~~~~~~~~~~
