fix(ansible): show cluster identity instead of first node in cluster_info (#44)

The Step 1 task used gather_subset: cluster/nodes and rendered
records[0].name, which is a node name (e.g. ...-vm-01), not the
cluster name. The version field was also omitted from fields, so
ONTAP returned no version data and the message showed 'unknown'.

Switch to gather_subset: cluster, request name and version, and
read from cluster_result.ontap_info.cluster. Output now matches
the Python example (Cluster: <name> - ONTAP <version>).
