this was the runtime version not the image one right? if so this is wrong (do image and runtime follow same release? if so this is still wrong to me, but righter...)

I think this change is right. It's using the runtime version
(specs.Version) to fill in a field on the generated runtime config.
With this PR, there's one less place to bump when image-tools moves to
new runtime-spec versions. Although with the approach made possible
by opencontainers/runtime-tools#219, we will be able to drop the
runtime-spec dependency completely.
