Acknowledge "always_auth" and "_authToken"

(for usage with private registries)

# .npmrc
always_auth = true
//<host>/:_authToken=<token>

Hey @leipert, has your pull request resolved this one as well? I am not sure what always_auth=true means

[leipert]

Yeah, it should work.
If your using the public npm registry, you do not need auth for GET requests.
But pnpm actually sets the token on each request which goes to a https:// registries, so always_auth is per se true when using pnpm and having saved credentials.

EDIT: So actually it was already closed with #161

Awesome! Thanks!
