Description

Set up a GitHub Action that automatically builds and generates a Storybook preview for every successful pull request (PR) build in the metamask-design-system repository. This will allow reviewers and stakeholders to easily access and preview component changes without needing to build the Storybook locally.

Technical Details

• Configure the GitHub Action workflow to trigger a Storybook build whenever a PR is successfully built.
• The Action should run on each PR and generate a deployable Storybook instance (e.g., hosted on a temporary environment or using a preview feature).
• Ensure the generated Storybook is linked in the PR for easy access by reviewers.
• The Storybook preview should be automatically discarded or disabled after the PR is merged or closed.
• Use tools such as Vercel, Netlify, or GitHub Pages preview to host the temporary Storybook build, depending on the existing infrastructure.

Acceptance Criteria

• A Storybook build is automatically generated and hosted for each successful PR build.
• The build is linked in the PR, making it accessible for review.
• The Storybook preview is automatically removed or archived once the PR is merged or closed.
• The workflow is reliable and does not block PR merging.
