Revert "ci: Enable workflow queue for publish-release workflow"

[Mrtenz]

Reverts #8640.

Temporarily reverting to see if this causes an issue with a workflow run.

---

Note

Medium Risk
Touches CI/release GitHub Actions configuration; mistakes could block releases or reduce workflow protection, though the changes are small and a direct revert.

Overview
Reverts the publish-release workflow concurrency configuration that enabled queued runs (removes queue: max and its group).

Deletes .github/actionlint.yml and downgrades the actionlint download in main.yml (script ref + version) to match the workflows’ supported syntax, avoiding the previous lint exception for the unsupported queue key.
