Fix image pattern for FedoraSecondary provider on s390x
Browse files Browse the repository at this point in the history 
Updated the image pattern in FedoraSecondaryImageProvider to match
the available Fedora image file names for the s390x architecture.
This resolves the issue where the vmimage utility could not download
the correct image due to a pattern mismatch.
