Making step definitions more generic

This scenario checks the disabled attribute as before, but this time testing that it is not set. Therefore, update our step definition at spec/cucumber/steps/assertions/index.js to take this into account:

When(/^the (?:"|')([\.#\w-]+)(?:"|') element should( not)? have a (?:"|')([\w_-]+)(?:"|') attribute$/, async function (selector, negation, attributeName) {  const element = await this.driver.findElement(By.css(selector));  const attributeValue = await element.getAttribute(attributeName);  const expectedValue = negation ? null : 'true';  assert.equal(attributeValue, expectedValue);});
