no-member for Generic class with new astroid 2.15.7

[altendky]

Bug description

I get a `no-member` error for attributes of a generic dataclass when running with the new astroid 2.15.7.  This is true for both pylint 2.17.5 and the new pylint 2.17.6.


$ cat p.py
# pylint: disable=missing-module-docstring invalid-name missing-class-docstring
from dataclasses import dataclass
from typing import Generic, TypeVar


T_Inner = TypeVar("T_Inner", bound="Inner")


@dataclass
class Inner:
    inner_attribute: str


@dataclass
class Outer(Generic[T_Inner]):
    inner: T_Inner


x = Outer(inner=Inner(inner_attribute="magic xylophone"))
print(x.inner.inner_attribute)

Thank you for opening the issue. I can reproduce on main (3.0.0b0)

This is probably the same issue as pylint-dev/astroid#2305, but keeping this open so we close it with a regression test in pylint.
