📋 General description or bullet points (if proposing new content)

The current documentation show us how to generate the content when using the getEntry method for one entry only:

In my current use case, I have a collection of entries that I want to be rendered on one page. After fiddling for a few hours, here is a similar example to the one provided for one entry. but for multiple entries:

---
import { getCollection } from 'astro:content';
const blogEntries = await getCollection('blog');
const renderedBlogEntries = await Promise.all(blogEntries.map(async (blogEntry) => {
    const { Content, headings } = await blogEntry.render();
    return { ...blogEntry, Content, headings };
}));
---
<div>
  {blogEntries.map(blogEntry => (
      <h1>{blogEntry.data.title}<h1>
      <blogEntry.Content />
    ))}
</div>

I'll make a StackBlitz example when I have the time but I wanted to share the solution first, so that anybody stuck on this problem can at least fix it if they find this issue.
