Registry URLs must include https://

[jcansdale]

Why:

Registry URLs must include https://. Without this, publish will fail with the following warning/error:

npm WARN invalid config registry="npm.pkg.github.com"
npm WARN invalid config Must be a full url with 'http://'
npm ERR! code E404
npm ERR! 404 Not Found - PUT https://registry.npmjs.org/@jcansdale-test%2fnpm-errors - Not found
npm ERR! 404

What's being changed:

Changing the highlighted line to include https://.
