False unsubscriptable-object positive with generic subprocess.Popen and __future__ annotations

[scop]

A variant of #4034, just with annotations imported on python 3.8. Per that issue, outputting the error is arguably correct if the from __future__ import annotations import is not present, but when it is, this should not result in an error.

I'm guessing (not tested) just adding subprocess.Popen to pylint.checkers.utils.SUBSCRIPTABLE_CLASSES_PEP585 would be a quick and dirty fix, but subprocess.Popen isn't actually mentioned in PEP 585 so it wouldn't feel quite right.

There might be some others similarly affected, mypy docs at https://mypy.readthedocs.io/en/stable/runtime_troubles.html#using-classes-that-are-generic-in-stubs-but-not-at-runtime mention os.PathLike and queue.Queue.

Steps to reproduce

from __future__ import annotations
from subprocess import Popen, PIPE

def foo(popen: Popen[str]) -> None:
    pass

foo(Popen(["ls"], stdout=PIPE))

Current behavior

t4.py:5:15: E1136: Value 'Popen' is unsubscriptable (unsubscriptable-object)

Expected behavior

No unsubscriptable-object

I'm not entirely certain if related, but I'm having the same issue with Column type from` the sqlalchemy typestubs
pylint 2.12.2
Python 3.9.6

from __future__ import annotations
from sqlalchemy import Column, DateTime, Integer, String

class Player(BaseModel):
    __tablename__ = "player"

    user_id = db.Column(db.String(8), primary_key=True)
    name = db.Column(db.String(32), nullable=False)
    # The biggest region code I found so far was "us/co/coloradosprings" at 21
    country_code = db.Column(db.String(24))
    score = db.Column(db.Integer, nullable=False)
    score_details = db.Column(db.String())
    last_update = db.Column(db.DateTime())
    rank: Optional[int] = None

    schedules = db.relationship("Schedule", back_populates="owner")
