chore(typing): Follup-up fix _from_array_like

Have a better understanding *now* of what the issue is in (https://github.com/narwhals-dev/narwhals/actions/runs/13577097131/job/37955718895).

- This patch is *functionally* the same - but removes the need for ignoring a (typing) warning following (narwhals-dev/narwhals@62f8a1f).
- Should also mean we don't need to bump our `narwhals` minimum [again](#3807 (comment)).
- **Bonus**: reduced overhead for `<3.11` (python/cpython#84403)
