conformance: dataclasses_inheritance.py - add missing # E

[KalininDL]

It seems that # E is missing in the snippet bellow

@dataclass
class DC5:
    # This should generate an error because a default value of
    # type list, dict, or set generate a runtime error.
    x: list[int] = []

Could you please take a look?

Thanks for the contribution. Yes, I agree this is missing an '# E'.
