fix(deploy): mount /data PVC into git-hook container

The git-hook worker needs /data to access repo storage paths, but the
deployment defined the shared-data PVC volume at pod level without
attaching it to the container via volumeMounts. Added the missing
volumeMounts block (name: shared-data, mountPath: /data) so the PVC is
properly mounted into the git-hook container, consistent with app and
static deployments.
