Use parenthesized_with_dangling_comments in arguments formatter (#6376

)

## Summary

Fixes an instability whereby this:

```python
def get_recent_deployments(threshold_days: int) -> Set[str]:
    # Returns a list of deployments not older than threshold days
    # including `/root/zulip` directory if it exists.
    recent = set()
    threshold_date = datetime.datetime.now() - datetime.timedelta(  # noqa: DTZ005
        days=threshold_days
    )
```

Was being formatted as:

```python
def get_recent_deployments(threshold_days: int) -> Set[str]:
    # Returns a list of deployments not older than threshold days
    # including `/root/zulip` directory if it exists.
    recent = set()
    threshold_date = (
        datetime.datetime.now()
        - datetime.timedelta(days=threshold_days)  # noqa: DTZ005
    )
```

Which was in turn being formatted as:

```python
def get_recent_deployments(threshold_days: int) -> Set[str]:
    # Returns a list of deployments not older than threshold days
    # including `/root/zulip` directory if it exists.
    recent = set()
    threshold_date = (
        datetime.datetime.now() - datetime.timedelta(days=threshold_days)  # noqa: DTZ005
    )
```

The second-to-third formattings still differs from Black because we
aren't taking the line suffix into account when splitting
(#6377), but the first
formatting is correct and should be unchanged (i.e., the first-to-second
formattings is incorrect, and fixed here).
