Set sidebar status from build result

[tmeasday]

Use the new experimental_updateStatus API to set the sidebar status as build results come in.

It's not totally clear what statuses we should be setting (success or unknown for passing/accepted tests?). There are a lot of details to work through, but the wiring is there.

Note to run this right now you need to install the addon into a sandbox on the release/7.2 branch, like so:

  addons: [
    '@storybook/addon-links',
    '@storybook/addon-essentials',
    '@storybook/addon-onboarding',
    '@storybook/addon-interactions',
    {
      name: '/Users/tom/GitHub/chromaui/addon-visual-tests/dist/index.js', // or similar
      options: {
        projectId: '64acdc2151cdda2cb8b7eaaf',
        projectToken: 'chpt_4c07aba6aed67ce',
      },
    },
  ],
