[Bug]: Svelte stories that use a decorator show <SlotDecorator> as source

[tmeasday]

Describe the bug

The Svelte snippet generator fails if you use a decorator.

To Reproduce

1. Start a Svelte sandbox.
2. Add a decorator

// .storybook/preview.js
import SomeDecorator from './SomeDecorator.svelte';

/** @type { import('@storybook/svelte').Preview } */
const preview = {
  parameters: {
    backgrounds: {
      default: 'light',
    },
    actions: { argTypesRegex: '^on[A-Z].*' },
    controls: {
      matchers: {
        color: /(background|color)$/i,
        date: /Date$/,
      },
    },
  },
  decorators: [() => SomeDecorator]
};

export default preview;

// .storybook/SomeDecorator.svelte
<div>
	decorated
	<slot/>
</div>

3. Open an autodoc and click "Show code"
4. See that the component name is always "SlotDecorator", which is incorrect.

System

No response

Additional context

SlotDecorator is an internal component used in the Svelte renderer.

Hi @tmeasday, can I help out fixing this issue? If so can you point me in the right direction, I haven't contributed to Storybook (yet). Thank you 🙏

@hugohaggmark sorry about the lack of response! I asked @JReinhold for his opinion and accidentally nerd sniped him into fixing it 😆 not my intention!
