feat: vcluster --version

[LukasGentele]

Would be good to be able to check the CLI version and potentially also useful to include a command or --server flag for the server side version of a vcluster

[FabianKramm]

Yes we can add a version flag, regarding the server version: this is quite difficult as you would need to somehow select which vcluster should be targeted. I guess this would be better displayed in the list command as proposed here #2

Can we not add a specific command such as: vcluster [vcluster_name] --version? Following the convention: APPNAME VERB NOUN --ADJECTIVE. or APPNAME COMMAND ARG --FLAG. Now, here since verb is not required, we can have the command structure as stated at the start.

[Joibel]

'vcluster --version' for the CLI version already exists. I'd say it was confusing to have the other syntax, and 'vcluster list' or 'vcluster info ' could do the job instead.

We decided to not implement this for now. Please comment if you feel like we should reconsider.
