`dataclasses.astuple` breaks on `DefaultDict`

[kwsp]

Bug report

This is very similar to #79721

from dataclasses import dataclass, astuple
from typing import DefaultDict, List
from collections import defaultdict

@dataclass
class C:
 mp: DefaultDict[str, List]

dd = defaultdict(list)
dd["x"].append(12)
c = C(mp=dd)
d = astuple(c) # throws "TypeError: first argument must be callable or None"


assert d == ({"x": [12]},)
assert d[0] is not c.mp # make sure defaultdict is copied

Basically applying the same fix for asdict from #32056 to astuple.
