Adapt release workflow test mocks to action-gh-release v3.0.2

[delthas]

What does this PR do, and why do we need it?

The check-workflows job fails on every PR based on development/2.14+ since 2026-07-13: softprops/action-gh-release v3.0.2 (picked up automatically via the floating @v3 tag in release.yaml) changed its GitHub API call sequence. Its findTagFromReleases now falls back to listing releases when getReleaseByTag returns 404 — GitHub does not expose draft releases through get-by-tag — and retries the listing up to 3 times. These extra listReleases calls eventually consumed the sequenced mock reply containing the draft release (intended for the post-creation canonicalizeCreatedRelease scan), so the action believed a release already existed and issued a PATCH /releases/123 with draft: true that no mock matches. The unmatched request hangs until undici's headers timeout, and the 5 "Promote artifacts" tests in release.spec.ts each died on the 120s jest timeout.

This PR replaces the sequenced listReleases replies with a single repeated draft-free reply, making the mocks independent of how many listing calls the action makes. The action then creates the release as before and discovers the created draft through the second getReleaseByTag reply alone (pickCanonicalRelease falls back to it when listings contain no match), before publishing it via the existing updateRelease mock.

Which issue does this PR fix?

Fixes ZENKO-5317.

Special notes for your reviewers:

• The exact call sequence was confirmed with a DEBUG=nock* trace: the release-notes step makes one listReleases call (the old mock comments claiming two were inaccurate), and the action's fallback makes three.

Issue: ZENKO-5317
