truthy-function incorrectly reported on sqlalchemy's hybrid_property with expression

[StephenPCG]

Bug Report

(A clear and concise description of what the bug is.)

To Reproduce

import sqlalchemy as sa
from sqlalchemy.orm import declarative_base
from sqlalchemy.ext.hybrid import hybrid_property


Base = declarative_base()


class Foo(Base):
    deleted_at = sa.Column(sa.DateTime(), nullable=True)

    @hybrid_property
    def is_deleted(cls) -> bool:
        return cls.deleted_at is not None

    @is_deleted.expression  # type: ignore[no-redef]
    def is_deleted(cls, v):
        return cls.deleted_at.is_not(None)


foo = Foo()

assert foo.is_deleted

Expected Behavior

mypy should report no error.

Actual Behavior

mypy reports the following error on the last line:

error: Function "Callable[..., Any]" could always be true in boolean context  [truthy-function]

BTW, if there is no @is_deleted.expression，just one @hybrid_property，mypy reports no error.

Your Environment

• mypy version: 0.991
• python version: 3.11.0
• sqlalchemy2-stubs version: 0.0.2a29
• mypy config (in pyproject.toml)
