Auto migration: From @storybook/<jest|testing-library> to @storybook/test

[vanessayuenn]

This automigration should do the following:

- import { expect } from '@storybook/jest';
- import { within, userEvent } from '@storybook/testing-library';
+ import { within, userEvent, expect, fn } from '@storybook/test';

Explicit action args are handled in #25904

Questions

• Which jest specific APIs do we want to transform to their vitest equivalent? (if any)
  -- jest.fn
  -- jest.spyOn
• Codemod or automigration?
