To Reproduce
Steps to reproduce the behavior.

Consider this piece of code

from dataclasses import dataclass
from typing import Final


@dataclass
class Foo:
    bar: Final[str] = "G.R. Emlin"

"Final" is not allowed in this context

Expected behavior
Final shouldn't be labeled as not allowed in this context
