Fixes: #1815

🎯 Changes

In React JSX.Element is only a subset of the valid children described by ReactNode. By widening this type we allow returning all valid React children now in a non-breaking fashion allowing

withForm({
  // Type 'null' is not assignable to type 'Element'.
  render: function Render() {
    return null
  },
})

withFieldGroup({
  // Type 'null' is not assignable to type 'Element'.
  render: function Render() {
    return null
  },
})

to work without TypeScript errors.
