CLN remove unnecessary trailing commas to get ready for new version of black
The new version of `black` is consistent in how it handles the magic trailing commas. So if we upgrade `black` and apply it, lots of files will be changed. However, the diff needn't be so large if we remove unnecessary trailing commas before upgrading.

E.g. in pandas/core/aggregation.py there is

```python
def reconstruct_func(
    func: Optional[AggFuncType], **kwargs,
) -> Tuple[
    bool, Optional[AggFuncType], Optional[List[str]], Optional[List[int]],
]:
```

which has an unnecessary trailing comma.

The new version of `black` would transform this as

```python
def reconstruct_func(
    func: Optional[AggFuncType],
    **kwargs,
) -> Tuple[bool, Optional[AggFuncType], Optional[List[str]], Optional[List[int]],]:
```

However, if we instead remove the trailing comma and write it as

```python
def reconstruct_func(
    func: Optional[AggFuncType], **kwargs
) -> Tuple[bool, Optional[AggFuncType], Optional[List[str]], Optional[List[int]]]:
```

then both the current and the new versions of black will be OK with it.

So, PRs to remove some unnecessary trailing commas would be welcome - perhaps keep each PR limited to 5-10 files changed.
