Fix jest-image-snapshot link

[yhor1e]

Issue: N/A

What I did

The link [jest-image-snapshot](https://github.com/storybookjs/storybook/tree/master/addons/storyshots#configure-storyshots-for-image-snapshots) is not correct. https://github.com/storybookjs/storybook/tree/master/addons/storyshots page doesn't have #configure-storyshots-for-image-snapshots content.

ref:

storybook/docs/writing-tests/visual-testing.md

Line 13 in 9399698

For a self-managed alternative to Chromatic, we offer [StoryShots](https://github.com/storybookjs/storybook/tree/master/addons/storyshots). It allows you to run visual tests on stories by integrating with [jest-image-snapshot](https://github.com/storybookjs/storybook/tree/master/addons/storyshots#configure-storyshots-for-image-snapshots).

I think https://github.com/storybookjs/storybook/tree/master/addons/storyshots/storyshots-puppeteer#imagesnapshots is correct and fix it.

Please merge this PR if you need or close it if you don't need.

Thank you for your time in advance.

How to test

• Is this testable with Jest or Chromatic screenshots?
• Does this need a new example in the kitchen sink apps?
• Does this need an update to the documentation?

If your answer is yes to any of these, please make sure to include it in your PR.
