Fix and *RETAIN* version check

[bomoko]

This PR addresses the logic issue with the overriding of the PersistentPreRun function in the command hierarchy that is leading to the inconsistent running of the version update check across commands.

Here we move this to the cobra OnInitialize() initializer's slice (some discussion on the differences are here, although not particularly useful - https://stackoverflow.com/questions/68766567/oninitialize-vs-persistentprerun-in-a-cobra-based-cli)

Closing issues

closes #487

Note - there is a second PR that will remove the functionality except for running in the "version" command explicitly (up to maintainer to choose).
