dataclass copy constructor doesn't recognize default_factory

Bug report
The dataclass copy constructor doesn't recognize the default_factory.

@dataclass
class Orig2:
    a: int
    b: int = 1
    c: List[int] = field(default_factory=list)

Copy2 = dataclass(Orig2)

Causes the following error`

Your environment
This bug has been shown to exist in versions 3.9 and 3.10. The test above is python 3.10.4.

Using the line numbers in python 3.10.4, this can be fixed with the following change to dataclasses.py line 958:

    for f in cls_fields:
        fields[f.name] = f

        # If the class attribute (which is the default value for this
        # field) exists and is of type 'Field', replace it with the
        # real default.  This is so that normal class introspection
        # sees a real default value, not a Field.
        if isinstance(getattr(cls, f.name, None), Field):
            if f.default is MISSING and f.default_factory is MISSING:      # <-- Add second test
                # If there's no default, delete the class attribute.
                # This happens if we specify field(repr=False), for
                # example (that is, we specified a field object, but
                # no default value).  Also if we're using a default
                # factory.  The class attribute should not be set at
                # all in the post-processed class.
                delattr(cls, f.name)
            else:
                setattr(cls, f.name, f.default_factory if f.default is MISSING else f.default)   # <-- add conditional
