Cypress.dom.isDetached missing from Typescript types

Current behavior:

The method Cypress.dom.isDetached() type errors in Typescript projects.

Desired behavior:

The method Cypress.dom.isDetached() does not type error in Typescript projects.

Steps to reproduce: (app code and test code)

1. Set up a Typescript Cypress project as described in https://docs.cypress.io/guides/tooling/typescript-support.html
2. Write the following test:

describe('Demonstrates bug', function() {
  beforeEach(() => {
    cy.setup();
  });
  
  it('demonstrates Typescript error'), function() {
    cy.get('button').then(($el) => {
      Cypress.dom.isDetached($el)
    });
  });
});

1. Get the following error:

Property 'isDetached' does not exist on type '{ isHidden(element: HTMLElement | JQuery<HTMLElement>): boolean; }'

@jennifer-shehane Do you mind if I pick this up? Also should we add all of the dom functions to the declaration file? It looks like there are a good deal more in dom/index.js that could be added.

@jennifer-shehane or @kylerob any progress on this? I have

"cypress": "^4.0.2",
"@types/node": "^10.12.18",
"typescript": "~3.7.2",
node -v 12.16.1

and I am still seeing this issue
