Incorrect typescript typings with addon-jest's withTests

[rakeshpai]

addDecorator(withTests({ results })); leads to a TypeScript error.

Argument of type '(args_0: string | (() => void), args_1: { kind: string; parameters: AddonParameters; }) => void | ((storyFn: () => void, { kind }: { kind: string; }) => void)' is not assignable to parameter of type 'StoryDecorator'.
  Types of parameters 'args_1' and 'context' are incompatible.
    Property 'parameters' is missing in type '{ kind: string; story: string; }' but required in type '{ kind: string; parameters: AddonParameters; }'.ts(2345)

It looks like the return type of withTests is not compatible with the accepted argument type of addDecorator.

To Reproduce
In a TypeScript project:

...
import { withTests } from '@storybook/addon-jest';
import results from '../jest-test-results.json';

...
addDecorator(withTests({ results }));

Dependencies
@storybook/react: 5.1.11
@storybook/addon-jest: ^5.1.11

@rakeshpai Is this fixed in 5.2? addon-jest got a nice overhaul from @CodeByAlex and I'm betting he fixed it 😆

@rakeshpai I’ll check on this and fix it if it doesn’t work

Just tried this with "@storybook/addon-jest": "^5.2.0-rc.11", and I get a very similar error (same code as before).

Argument of type 'DecoratorFunction<unknown>' is not assignable to parameter of type 'StoryDecorator'.
  Types of parameters 'c' and 'context' are incompatible.
    Type '{ kind: string; story: string; }' is missing the following properties from type 'StoryContext': id, name, parametersts ts(2345)

Thanks for looking into this!
