title: Disable Unnecessary escape character: \/ no-useless-escape
body: <p>I have this regex of mine that will check the string if it contains link or url <code>(i.e. https://eslint.org/docs/rules/no-useless-escape)</code>. Using this regex <code>/(\b(https?|ftp|file):\/\/[-A-Z0-9+&amp;@#\/%?=~_|!:,.;]*[-A-Z0-9+&amp;@#\/%=~_|])/ig</code>, I've encountered and error while running my test cases in react about <code>Unnecessary escape character: \/                    no-useless-escape</code>. How to disable this eslint-error in order for me to proceed with my test case and use the regex.</p>
  
  <p>Appreciate for any help!</p>
