fix: enable --query parameter support for aks show command

The aks show command was ignoring the --query flag and returning
the entire cluster JSON. This fixes the issue by:

1. Updating Show() to accept *cobra.Command parameter
2. Using output.PrintJSON() helper for query filtering
3. Passing cmd parameter from command definition

Now queries like --query 'properties.addonProfiles.azureKeyvaultSecretsProvider'
will correctly filter the output.

Fixes issue where nested property queries were not working.
