Incorrect SvelteComponent type for Svelte 4?

[jenseo]

Describe the issue you're facing

Hello, we are right now migrating our project to Svelte 4, but have a typing issue that seems to be coming from @storyblok/svelte.

According to the migration guide section here:

https://svelte.dev/docs/v4-migration-guide#sveltecomponenttyped-is-deprecated

...the typeof SvelteComponent instance now need to be typed like this: typeof SvelteComponent<any>

I believe the type here has to be changed from typeof SvelteComponent to typeof SvelteComponent<any>:

https://github.com/storyblok/storyblok-svelte/blob/main/lib/pkg/types.ts#L4C1-L6C2

Without this change, when we initialize our components in storyblokInit like this:

import Article from '$lib/components/Article.svelte';

storyblokInit(
    {
    ...
        components: {
            Article,
        }
    ...
    }
)

...we get the following type error:

Type 'typeof Article__SvelteComponent_' is not assignable to type 'typeof SvelteComponent'.
  Types of construct signatures are incompatible.
    Type 'new (options: ComponentConstructorOptions<{ blok: ArticleStoryblok; }>) => Article__SvelteComponent_' is not assignable to type 'new <Props extends Record<string, any> = any, Events extends Record<string, any> = any, Slots extends Record<string, any> = any>(options: ComponentConstructorOptions<Props>) => SvelteComponent<...>'.
      Types of parameters 'options' and 'options' are incompatible.
        Type 'ComponentConstructorOptions<Props>' is not assignable to type 'ComponentConstructorOptions<{ blok: ArticleStoryblok; }>'.
          Type 'Props' is not assignable to type '{ blok: ArticleStoryblok; }'.
            Property 'blok' is missing in type 'Record<string, any>' but required in type '{ blok: ArticleStoryblok; }'
