Reproduction steps

configure a private registry in pnpm-workspace.yaml like so:
registry: <your private registry URL>

do NOT configure that in any npm-configuration (no /etc/npmrc, no ~/.npmrc, no ./.npmrc)

enter pnpm login to authenticate against your private registry

Describe the Bug

pnpm delegates to npm which doesn't know about pnpm-workspace.yaml, so instead tries to authenticate against default registry:

npm notice Log in on https://registry.npmjs.org/

Expected Behavior

pnpm login should authenticate against configured private registry.
