Ensure Node Auth Secret is used whilst publishing #33
Description
The attempt to publish with the NODE_AUTH_TOKEN secret failed:
npm error code ENEEDAUTH
npm error need auth This command requires you to be logged in to https://registry.npmjs.org/
...It sounds like @actions/setup-node requires the registry-url to be set otherwise the secret isn't used?
Plus, we should set always-auth: true, to match @asos/snyker, for good measure.
