Overlay2 is no longer installed in Docker by default (because it's deprecated)

Following up on Overlayfs to Overlay2, Failed on Fresh Installation, storage driver

I whined over on

Overlay2 not enabled by default with get.docker.com on Ubuntu LTS. 24.04

And it seems that overlay2 is not installed anymore:

This is no accident:

• As of Docker Engine v29, the containerd image store becomes the default for image layer and content management for new installs.
• Legacy graph drivers are still available, but are now deprecated. New installs can still opt out of Containerd image store if there is any issue.

So I guess either Discourse needs to move to a new image thingy?
