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.
