`converter` type in attrs not correctly passed on to `__init__`

[pvandyken]

Describe the bug In pyright 1.1.358, the generated __init__ types for attrs-wrapped classes no longer respect functions or constructors provided to the converter argument of attrs.field. The now-expected type seems to vary depending on the converter, I haven't found an exact pattern. Simple converters like str seem to work fine.

Code or Screenshots

# test.py
from __future__ import annotations

import attrs

@attrs.define
class A:
    a: dict[str, str] = attrs.field(converter=dict)


test = A(a={"foo": "bar"})
