[ruff-0.9] Stabilise slice-to-remove-prefix-or-suffix (FURB188) (#…

…15329)

Stabilise [`slice-to-remove-prefix-or-suffix`](https://docs.astral.sh/ruff/rules/slice-to-remove-prefix-or-suffix/) (`FURB188`) for the Ruff 0.9 release.

This is a stylistic rule, but I think it's a pretty uncontroversial one. There are no open issues or PRs regarding it and it's been in preview for a while now.
