PF4: Missing Modal Typing

[dlabrecq]

Encountered another type errors with the Modal from @patternfly/react-core v1.8.1.

TS2305: Module '"/Users/dlabrecq/Work/hccm/repos/koku-ui/node_modules/@patternfly/react-core/dist/js/index"' has no exported member 'Modal'

My workaround is to import like so:

import {
  Alert,
  AlertVariant,
  Button,
  ButtonVariant,
// Modal,
} from '@patternfly/react-core';

import { Modal } from '@patternfly/react-core/dist/js/components/Modal';
