Use internal pkgs.dev.azure.com registry for AzureCliConfigDir lockfile

The repo's CI 'Verify registries' check rejects package-lock.json files
that resolve from registry.npmjs.org. Add the standard .npmrc (mirroring
Tasks/Common/coveragepublisher) and regenerate package-lock.json so all
resolved URLs point to PipelineTools_PublicPackages.
