add second set of tests

[iambumblehead]

please review this small PR

This PR adds the second set of example esm export patterns from nodejs' documentation site here https://nodejs.org/api/packages.html#package-entry-points

{
  "name": "my-package",
  "exports": {
    ".": "./lib/index.js",
    "./lib": "./lib/index.js",
    "./lib/*": "./lib/*.js",
    "./lib/*.js": "./lib/*.js",
    "./feature": "./feature/index.js",
    "./feature/*": "./feature/*.js",
    "./feature/*.js": "./feature/*.js",
    "./package.json": "./package.json"
  }
}

The tests are maybe a little easy and better tests could be added later. Some resolutions were verified with something like this, not committed,

const imported = await import( 'nodejsexample_02_exports/lib' );
