ci: Automated update vc-frontend from PR 2156 VirtoCommerce/vc-frontend#2156

---

Note

Low Risk
Low risk because this only changes the theme package download location/version used by deployment; risk is limited to pulling an incorrect or incompatible artifact.

Overview
Updates theme/artifact.json to reference a new vc-theme-b2b-vue pre-release artifact (2.41.0 from vc-frontend PR 2156) instead of the prior 2.40.0 GitHub release URL.
