[New-bugs-announce] [issue46345] Add an explicit test for `get_type_hints` for a class field with `None` default

[Nikita Sobolev]

New submission from Nikita Sobolev <mail at sobolevn.me>:

Right now this corner case is not tested:

```python
class Some:
    x: int = None

import typing
assert typing.get_type_hints(Some) == {'x': int}
```

Notice that we don't add implicit `Optional` type to `x`. This is different for function arguments that will have `Optional` added.

I think it is a good idea to add a test for this. Espeically given that we can change function's behavior.
