 * When declaring dependencies in a package.json file, it's possible to specify
 * an "alias".
 *
 * An example of this would be:
 *
 * @example
 * ```json
 * {
 *   "dependencies": {
 *     "my-alias": "npm:is-positive@^1.0.0"
 *   }
 * }
 * ```
 *
 * This function normalizes out the alias and returns the real package name
 * (i.e. "is-positive" for this example) if "npm:" is used.
