Prefer append over appendChild

Enforces the use of, for example, document.body.append(div); over document.body.appendChild(div); for DOM nodes. There are some advantages of using .append(), like the ability to append multiple nodes and to append both DOMString and DOM node objects.

This rule is fixable.

Fail

foo.appendChild(bar);

Pass

foo.append(bar);
foo.append('bar');
foo.append(bar, 'baz');
