Add GitHub workflow to update vcpkg dependencies (#184)

This workflow triggers on changes to vcpkg.json or vcpkg-configuration.json in the main branch. It sets up vcpkg, bootstraps it, and performs a dry-run to build the dependency graph. This ensures dependency updates are tracked and managed automatically.
