Host storybook-react-native for metamask-design-system on GitHub Pages with Auto-Update on Merges to main

### **Description**

We need to host `storybook-react-native` for the `metamask-design-system` React component library on a GitHub page. This Storybook should be automatically updated whenever changes are merged into the `main` branch to ensure that the documentation reflects the latest updates.

### **Technical Details**

- Configure the GitHub repository to deploy Storybook to GitHub Pages.
- Set up GitHub Actions or a similar CI/CD pipeline to automatically build and publish Storybook on any merge to the `main` branch.
- Ensure that the deployment happens smoothly and the hosted Storybook reflects all the latest updates from the `metamask-design-system` repository.
- Verify that the Storybook documentation is accessible through a consistent, public URL (e.g., via `https://metamask.github.io/metamask-design-system/`).

### **Acceptance Criteria**

- Storybook for the `metamask-design-system` is hosted on GitHub Pages.
- The hosted Storybook is automatically updated whenever changes are merged to the `main` branch.
- The deployment process is stable and ensures no downtime during updates.
- Stakeholders can review the deployed Storybook without needing local setup.
