Use lighter weight VM images in tests #91
Description
Test scripts currently use these images:
- quay.io/containerdisks/fedora:40
- quay.io/crun-vm/example-fedora-coreos:40
- quay.io/fedora/fedora-bootc:40
They take a while to import into the test harness VM and to boot. We could replace these by lighter weight images so our tests run quicker.
