Add Storybook template components for Svelte Vite CLI

Add Button, Header, and Page components with stories for multiple Svelte variations:
- JavaScript
- Svelte 5 JavaScript

+    <p>
+      Render pages with mock data. This makes it easy to build and review page states without
+      needing to navigate to them in your app. Here are some handy patterns for managing page data
+      in Storybook:
+    </p>
+    <ul>
+      <li>
+        Use a higher-level connected component. Storybook helps you compose such data from the
+        "args" of child component stories
+      </li>
+      <li>
+        Assemble data in the page component from your services. You can mock these services out
+        using Storybook.
+      </li>
+    </ul>
