Don't wrap | None on a new line

[Olegt0rr]

Describe the style change

I don't like current behavior on documented FastAPI handlers.

@router.get("/path")
async def some_handler(
    can_restrict_members: bool | None = Query(None, description="Can restrict members?"),  # the line is toooooo long
):
    ...

Examples in the current Black style

async def some_handler(
    can_restrict_members: bool
    | None = Query(
        None,
        description="Can restrict members?",
    ),
):
    ...

Desired style

async def some_handler(
    can_restrict_members: bool | None = Query(
        None,
        description="Can restrict members?",
    ),
):
    ...

Thanks, duplicate of #2316. (I agree this style is ugly and we should change it. PRs welcome!)
