How to identify Barman version being used by Barman Plugin in the running CNPG cluster ?

It was possible to find out Barman version with Barman Native with the command like:

kubectl -n $name_space exec -it $cluster_name-1 -- barman-cloud-backup --version

Is there a way to find out Barman version with Barman Plugin ?

Start with the documented kubectl command for Barman Native and inspect how the Barman Plugin runs in the CNPG cluster. Determine whether the plugin exposes a version that can be queried, and document a reliable way to identify it if one exists.
