Multiple collections (v3)

// content.config.ts
export default defineContentConfig({
  collections: {
    blog: defineCollection({ type: 'page', source: 'blog/**' }),
    docs: defineCollection({ type: 'page', source: 'docs/**' }),
  },
})

<!-- Blog post TOC -->
<TableOfContents path="/blog/hello" collection="blog" />

<!-- Docs TOC -->
<TableOfContents path="/docs/intro" collection="docs" />

Or pass-in after fetching from the right collection.
