Summary:
The version of npm available in Circle CI is 6.x, which does not support the `--pack-destination` argument. As a result, `npm pack --pack-destination build` was interpreted as a request to package the 'build' directory for distribution.
Since we need to make sure the output of `npm pack` is consumed by Circle CI's `store_artifacts` directive, we move the commitlies release packing logic to the Circle CI job config itself as to reduce coupling between `publish-npm.js` and the Circle CI config.
