Add vcpkg secrets check to CI workflow

Added a step in ResInsightWithCache.yml to verify that the required AZURE_VCPKG_STORAGE_ACCOUNT and AZURE_VCPKG_SAS_TOKEN secrets are set before running the configure step. This ensures the workflow fails early with a clear error if these secrets are missing, improving reliability and debuggability.
