Do not use module.parent for resolving rule name

[sudo-suhas]

module.parent is cached after the first require and this results in nearly all rules having the URL to assertion-arguments. Here's a simple repro:

'use strict';

const { rules } = require('eslint-plugin-ava');

const wrongLinks = [];

for (const ruleName of Object.keys(rules)) {
    const rule = rules[ruleName];
    const { url } = rule.meta.docs;
    if (!url.includes(ruleName)) wrongLinks.push(ruleName);
}

console.log(wrongLinks);

λ node rule-docs-url.js
[ 'max-asserts',
  'no-async-fn-without-await',
  'no-cb-test',
  'no-duplicate-modifiers',
  'no-identical-title',
  'no-ignored-test-files',
  'no-invalid-end',
  'no-nested-tests',
  'no-only-test',
  'no-skip-assert',
  'no-skip-test',
  'no-statement-after-end',
  'no-todo-implementation',
  'no-todo-test',
  'no-unknown-modifiers',
  'prefer-async-await',
  'prefer-power-assert',
  'test-ended',
  'test-title',
  'use-t-well',
  'use-t',
  'use-test',
  'use-true-false' ]

@sudo-suhas Thanks :) Would you be able to do the same change on https://github.com/sindresorhus/eslint-plugin-unicorn/blob/master/rules/utils/get-docs-url.js too?

Sure, will do it by tomorrow.
