Fails eslint node/no-unpublished-require validation

I noticed this in a project recently, the rule is documented here:
https://github.com/mysticatea/eslint-plugin-node/blob/master/docs/rules/no-unpublished-require.md

The issue seems clear to me that its simply missing both the the below requirements:

### Rule Details
If a source code file satisfies all of the following conditions, the file is *published*.

- "files" field of package.json includes the file or "files" field of package.json does not exist.
- .npmignore does not include the file.

Start with package.json and .npmignore, then compare the repository's publishing rules with the linked no-unpublished-require documentation and the ESLint report. Done means the reported validation failure is resolved and the rule passes for the repository.
