Before You File a Bug Report Please Confirm You Have Done The Following...

• [X] I have tried restarting my IDE and the issue persists.
• [X] I have updated to the latest version of the packages.

What version of ESLint are you using?

8.43.0

What version of eslint-plugin-svelte are you using?

2.32.0

What did you do?

Configuration

```json { "svelte/experimental-require-slot-types": "error" } ```

<script lang="ts">
    type $$Slots = {
        default: Record<string, never>;
    };
</script>

<slot />

What did you expect to happen?

Rules should be satisfied because RFC and Svelte language server works with type aliases as well. The declarations are correctly picked up and enforced by language server.

What actually happened?

1:2 error The component must define the $$Slots interface svelte/experimental-require-slot-types
