`WPS457` false positive with `while` in `try` / `except`

I have the following code:

```python
def factory() -> Iterator[bytes]:
    try:
        while True:  # noqa: WPS457
            yield async_to_sync(async_anext)(iterator)
    except StopAsyncIteration:
        pass
```

It should not raise `WPS457`, because `while` is in `try` / `except`.
It can clearly raise and we handle the error. So, it is not infinite.

PRs are welcome! 👍
