Fix npm publishing

Npm's CLI is broken because it doesn't respect the auth token being
provided via the environment when publishing despite npm/cli#8

GitHub's node action is broken because it doesn't respect the scope and
registry config as provided via package.json.

And npmjs.org registry is broken because it doesn't support named
tokens, nor tokens that skip OTP. Ergo, in order to publish via github
actions, my user profile 2fa must be downgraded to auth-only and the
package 2fa must be disabled.

OMFG
