Why are these changes needed?

Currently these container tests fail after #53783. This is because the docker version on the large instance containers is new and incompatible with the old podman version installed by default with apt-get. Moving it back to the medium instances fixes this because of the older docker version.

Installing a newer podman on ubuntu seems non-trivial and still deciding between upgrading podman or downgrading docker on the large instance containers.

Talked to @khluu about downgrading docker. In the meantime, just moving this back to medium so at least the tests start passing and it's no longer a release blocker.

How come the tests pass now on the medium size instance?
