chore(workflows): pre-merge changelog-trigger permission from master

[leaanthony]

Summary

Adopts a workflow change that already exists on master so the eventual v3-alpha → master merge has one fewer conflict to hand-resolve.

• .github/workflows/unreleased-changelog-trigger.yml — add the actions: write permission needed by the trigger step (already in place on master).

Erratum

An earlier commit on this branch also touched auto-label-issues.yml in the wrong direction (master's older pull_request accidentally copied over v3-alpha's pull_request_target); that has been reverted in commit bebdcf77. The correct fix for that file goes onto master, not v3-alpha — see the companion PR for master-side workflow pre-merges.

Test plan

• CI green
• Net diff vs v3-alpha is the single actions: write line in unreleased-changelog-trigger.yml.

🐰 A single line, so small yet grand,
Actions write now at hand!
Release the workflows, set them free,
With permissions new, oh what will be! ✨🚀
