When the container with osbuild-composer gets built in our CI or by
AppSRE, we do not set the composer version to any value (as we do when
we built RPMs). As a result, the version reported by composer is always
"devel". This is not useful for debugging and determining the used
version of composer. In addition, this information now gets exposed in
Koji builds, therefore it makes sense to make it useful.
