ci: Automated update vc-frontend from PR 2182 VirtoCommerce/vc-frontend#2182

---

Note

Low Risk
Single JSON value change that only affects which theme artifact is deployed; no code or logic changes.

Overview
Updates theme/artifact.json to point the theme artifact URL at a newer prerelease package (vc-theme-b2b-vue-2.42.0 from PR 2182) instead of the previous PR build.
