Issue 50758 - Need to enable CLI arg completion
    
    Bug Description:
    
    `activate-global-python-argcomplete` creates a file that belongs to
    another package. We shouldn't do that.
    
    Fix Description:
    
    Don't call `activate-global-python-argcomplete` as the completion is
    active by default when `python3-argcomplete` is installed on a system.
