## Summary

This PR improves the parentheses handling for with items to get closer
to black's formatting.

### Case 1:

```python
# Black / Input
with (
    [
        "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
        "bbbbbbbbbb",
        "cccccccccccccccccccccccccccccccccccccccccc",
        dddddddddddddddddddddddddddddddd,
    ] as example1,
    aaaaaaaaaaaaaaaaaaaaaaaaaa
    + bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
    + cccccccccccccccccccccccccccc
    + ddddddddddddddddd as example2,
    CtxManager2() as example2,
    CtxManager2() as example2,
    CtxManager2() as example2,
):
    ...

# Before
with (
    [
        "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
        "bbbbbbbbbb",
        "cccccccccccccccccccccccccccccccccccccccccc",
        dddddddddddddddddddddddddddddddd,
    ] as example1,
    (
        aaaaaaaaaaaaaaaaaaaaaaaaaa
        + bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
        + cccccccccccccccccccccccccccc
        + ddddddddddddddddd
    ) as example2,
    CtxManager2() as example2,
    CtxManager2() as example2,
    CtxManager2() as example2,
):
    ...
```

Notice how Ruff wraps the binary expression in an extra set of
parentheses


### Case 2:
Black does not expand the with-items if the with has no parentheses:

```python
# Black / Input
with aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa + bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb as c:
    ...

# Before
with (
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa + bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb as c
):
    ...
```

Or 

```python
# Black / Input
with [
    "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
    "bbbbbbbbbb",
    "cccccccccccccccccccccccccccccccccccccccccc",
    dddddddddddddddddddddddddddddddd,
] as example1, aaaaaaaaaaaaaaaaaaaaaaaaaa * bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb * cccccccccccccccccccccccccccc + ddddddddddddddddd as example2, CtxManager222222222222222() as example2:
    ...

# Before (Same as Case 1)
with (
    [
        "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",
        "bbbbbbbbbb",
        "cccccccccccccccccccccccccccccccccccccccccc",
        dddddddddddddddddddddddddddddddd,
    ] as example1,
    (
        aaaaaaaaaaaaaaaaaaaaaaaaaa
        * bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
        * cccccccccccccccccccccccccccc
        + ddddddddddddddddd
    ) as example2,
    CtxManager222222222222222() as example2,
):
    ...

```
## Test Plan

I added new snapshot tests

Improves the django similarity index from 0.973 to 0.977
