Because we add the runc-$version/ prefix to the archive we generate, including the version in the name makes it easier for some tools to operate on as it matches most other projects (for openSUSE we rename the archive file to this format in order for the automated RPM scripts to work properly). Also, when doing several releases at the same time, being able to double-check that the correct artefact versions were uploaded for each release can be quite handy.
