Xuehai Pan c73a92fbf5 [BE][CI] bump ruff to 0.9.2: multiline assert statements (#144546)
Reference: https://docs.astral.sh/ruff/formatter/black/#assert-statements

> Unlike Black, Ruff prefers breaking the message over breaking the assertion, similar to how both Ruff and Black prefer breaking the assignment value over breaking the assignment target:
>
> ```python
> # Input
> assert (
>     len(policy_types) >= priority + num_duplicates
> ), f"This tests needs at least {priority+num_duplicates} many types."
>
>
> # Black
> assert (
>     len(policy_types) >= priority + num_duplicates
> ), f"This tests needs at least {priority+num_duplicates} many types."
>
> # Ruff
> assert len(policy_types) >= priority + num_duplicates, (
>     f"This tests needs at least {priority + num_duplicates} many types."
> )
> ```
