[Node] Fix Module File Inclusion Issue (#24)

When this was pulled in as a dependency, it did not include all the
files necessary to work. Found the problem and fixed it.

## Changes

- Updated the package.json file to handle the file inclusions properly

## Checklist

- [ ] If changes were made to `validations.yaml`, make sure that `yarn
install && yarn build` has been run from the root of the repo and the
results committed
