Proposed Changes

• Send bump stats to an intermediate public-api.wordpress.com API endpoint so that we can determine if the request originated from inside A8C's network. If so, mark the stat as a11n.

This is not the latest version of node-fetch. I chose it because it already exists in our dependency tree.

The proposed changes look good to me and work as expected. I shared more feedback in the related backend PR.
