Migrate repo to Newfold labs org

Proposed changes

This changes the update url to the new endpoint.

This is in preparation for migrating the repo to the newfold-labs org. Once this merge is integrated and a release is tagged, the distributed plugin installations will begin looking for updates at the new URL and immediately find the major update.

See https://jira.newfold.com/browse/PRESS10-41 and newfold-labs/wp-plugin-bluehost#1

Tested this build and see the new release from the newfold-labs repo 4.0.0 and tested updating. All looks fine, plugin page loads and marketplace items and entitlements all load fine too. Still needs more testing, but the basic update path is now tested and functional!
