The prepare_public_folder.sh is only used in the update-playground CI. This has been failing for a long time and still fails. I believe the issue is not only with the origin, but there are other things we need to debug.

I have a WIP PR for this: #1215 (this is still not enough, I need to prioritize and debug it further)
