Description

Same reasoning as #43981:

• UP038 was deprecated since March 2025 https://astral.sh/blog/ruff-v0.10.0#rule-deprecations and removed in September 2025 https://astral.sh/blog/ruff-v0.13.0#rule-removals
• this repo is still using older ruff version 0.8.0, but this change will help prepare to version bump in the future

Line 38 in 6f9070a

rev: v0.8.0

• this repo used to be part of ruff-ecosystem check - basically comparing differences before and after changes in ruff on the real code to see what effect they have on Python ecosystem. It was commented out a while a go because removed E999 rule was used - this rule no longer an issue, but UP038 is a new blocker.

    # Disabled due to use of explicit `select` with `E999`, which has been removed.
