Storybook 5.2 has issues with TypeScript types

Describe the bug If I upgrade from 5.1 to 5.2, I start getting TypeScript errors in my project:

Module '".../node_modules/@storybook/react/dist/client"' has no exported member 'RenderFunction'.

13 import { RenderFunction } from '@storybook/react';
            ~~~~~~~~~~~~~~

According to issue #8160, we’re supposed to remove all @types/storybook... packages, but that makes things worse:

node_modules/@storybook/react/dist/client/preview/index.d.ts:2:23 - error TS2688: Cannot find type definition file for 'webpack-env'.

2 /// <reference types="webpack-env" />
                        ~~~~~~~~~~~

error TS7016: Could not find a declaration file for module '@storybook/addon-knobs/react'. '.../node_modules/@storybook/addon-knobs/react.js' implicitly has an 'any' type.
  Try `npm install @types/storybook__addon-knobs` if it exists or add a new declaration (.d.ts) file containing `declare module '@storybook/addon-knobs/react';`

1 import { text, select } from '@storybook/addon-knobs/react';
                               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Where are we supposed to be getting the types from? Neither the Storybook package nor the @types package seems to have all the updated types.

@hipstersmoothie @dawidk92 i’ll patch those over to master soon and cut a release, probably next week

On top of removing the unnecessary types definition files, I found I need to update how to get the API from

import {withKnobs, number} from '@storybook/addon-knobs/react';

to

import {withKnobs, number} from '@storybook/addon-knobs';
