ci: refresh pytest-split .test_durations

[github-actions]

Description

Automated refresh of .github/.test_durations (pytest-split shard balancing for test-ops).

Triggered because the ops test set changed in the nightly run:
+32 test(s) added, -0 removed.
Pure timing drift does not trigger this PR. Review and merge to keep the shards balanced.

CI Configuration

config:
  build: true
  # valid options are "ops", "benchmark", and "sanity"
  test: ["ops"]

Checklist

• Code formatted and imports sorted via repo specifications (./format.sh) — N/A, data-only change
• Documentation updated (if needed) — N/A
• CI configuration reviewed
