Fix F.resolve_expression() return type #1659

I have made things!

No issues raised.

When attempting to write a non-trivial django Field subclass, I needed to override the resolve_expression method, but discovered at that time that the stubs for that method are incorrect.

This method calls query.resolve_ref, which in turn returns either a Ref or something else, however I cannot see that it can ever return an F object itself (as that would defeat the purpose of the method, which is to resolve the references, and F is by definition an unresolved reference).

Are you 100% sure it always returns Ref and not other Expression subclasses?

Query.resolve_ref() is hinted to return Expression, so seems safer to go with that here. But I'm not at all familiar with this code.

Since I'm planning to do a release soon, I'll go ahead and merge this with -> Expression for now, which is already an improvement.

If you believe this should be constrained further to Ref, please do open another pull request.

#### Headline changes

-   **mypy 1.7:** Recommended mypy version updated to 1.7.x
- Improved type inference for `ManyToManyField` and
`Model.<manytomany>.through`
- If you previously imported `RelatedManager` or `ManyRelatedManager`,

RelatedManager`
- It's now allowed to override Django's `@cached_property` properties
with class variables or `@property` properties.

**Full Changelog**:
typeddjango/django-stubs@4.2.4...4.2.5

###
[`v4.2.4`](https://togithub.com/typeddjango/django-stubs/releases/tag/4.2.4)

[Compare
Source](https://togithub.com/typeddjango/django-stubs/compare/4.2.3...4.2.4)

Most important changes:

- This version add Mypy `1.5.*` support and update `[compatible-mypy]`
extra to use `1.5.*`.
- We also update our stubs to be compatible with Django `4.2.5` (and all
prior versions of `4.2`).
- `django_stubs_ext/` folder was renamed to be just `ext/`, it should
not affect users (unless you install it from git)
- We no longer assume the `objects` attribute to be present on generic
Model classes. As per the [django
documentation](https://docs.djangoproject.com/en/4.2/topics/db/managers/#django.db.models.Model.\_default_manager),
code working with generic models should use the `_default_manager`
attribute instead.

This time there is no corresponding release of `django-stubs-ext`.

#### Plugin changes

- We now forbid to instantiate abstract models

- Manager attributes are now `ClassVar`s
