Images are not properly migrated to the playground version (causing errors)

[juanmaguitar]

I created a custom repo based on bgrgicak/playground-blog proof of concept. My repo is available at wordpress-juanmaguitar/playground-blog

in that repo I created a few markdown posts, under the posts folder, some of them were using images from a posts/assets folder (the repo at that state can be seen at with-images branch)

When I launch the playground using the new blueprint:

• it gets stuck at "Loading posts,"
• I get the following error (see also spanshot)

TypeError: Cannot read properties of undefined (reading 'registerPlugin')
