spread.yaml: switch to using ubuntu-image from latest/edge

[alfonsosanchezbeato]

Now ubuntu-image is statically compiled so the issues with libc should be gone. Also, it has been detected that 2/stable creates partitions with unsupported features in older systems as it is shipping mkfs.ext4 in the snap, which comes from 20.04, but the one in latest is not shipping it.

Thanks for the reviews - I'm converting this to draft. I wonder if maybe we should move forward with using track 2 for UC16 and latest for the rest.

+1 on this approach.
