Issue: [Bug]: The `IconGallery` doesn't work with SvelteKit
Labels: bug,svelte,block: other

### Describe the bug

At https://storybook.js.org/docs/svelte/writing-docs/doc-block-icongallery, there's an example that shows how to use an `IconGallery`. However, when I try to use it with SvelteKit, it just crashes.

Example:

```mdx
import { Meta, Title, IconGallery, IconItem } from '@storybook/addon-docs'
import AcademicCap from '../lib/heroicons/20/solid/academic-cap.svelte'

<Meta title="Heroicons/Mini" />

# Mini

<IconGallery>
	<IconItem name="academic-cap">
		<AcademicCap />
	</IconItem>
</IconGallery>
```

Log:

```jsx
Warning: ReactDOM.render is no longer supported in React 18. Use createRoot instead. Until you switch to the new API, your app will behave as if it's running React 17.
