ci: Automated update vc-frontend from PR 2157 VirtoCommerce/vc-frontend#2157

---

Note

Low Risk
Low risk: a single configuration change that only affects which theme artifact is fetched/deployed.

Overview
Updates theme/artifact.json to replace the vc-theme-b2b-vue download URL from the 2.40.0 GitHub release to a 2.41.0 prerelease package (pr-2157), changing what artifact CI/deploy pulls.
