Bug description

Report from @TomSweeneyRedHat :

I just posted a link to the Podman Desktop 1.3 announcement from this
page: https://podman-desktop.io/blog/podman-desktop-release-1.3, and
when I posted it to Twitter:

https://twitter.com/Podman_io/status/1693626155989946406

There isn't a default Podman Desktop image as I would have expected. 
Can this be changed for the future?

This is something to do with Docusaurus. Looking at the Docusaurus docs, it appears there's an image attribute that gets used for this:

---
title: Welcome Docusaurus v2
description: This is my first post on Docusaurus 2.
slug: welcome-docusaurus-v2
authors:
  - name: Joel Marcey
    title: Co-creator of Docusaurus 1
    url: https://github.com/JoelMarcey
    image_url: https://github.com/JoelMarcey.png
  - name: Sébastien Lorber
    title: Docusaurus maintainer
    url: https://sebastienlorber.com

tags: [hello, docusaurus-v2]

hide_table_of_contents: false

It looks like the 1.13 blog doesn't have an image attribute:

---
title: Release Notes - Podman Desktop 1.3
description: Podman Desktop 1.3 has been released!
slug: podman-desktop-release-1.3
authors: [dgolovin]
tags: [podman-desktop, release, kubernetes, openshift]
hide_table_of_contents: false
---

This might be as simple as adding the image attribute to the header metadata of the post, but I need to figure out how to test it locally bc it seems by default docusaurus isn´t generating / sending the metadata for local yarn builds. I might need to set up a ghpages thing to test.
