CountsDict.__init__() passes *kwargs instead of **kwargs to super().__init__()

[王鑫]

The CountsDict class in django/utils/html.py has a bug in its init method:

class CountsDict(dict):

def init(self, *args, word, kwargs):

super().init(*args, *kwargs) # BUG: should be kwargs
self.word = word

The call uses *kwargs (positional unpacking) instead of kwargs (keyword unpacking). Currently this never triggers because CountsDict is only called with
word=middle, but it would fail if any keyword arguments were passed.

The fix is to change *kwargs to kwargs on line 281.
