Remove `helm package -u` in favor of `helm package` (#11769)
Remove `helm package -u` in favor of `helm package` (#11769)

This work removes the ability to include packages from
external helm repositories.  This is to remove the
`helm dep update` step.

The hidden implication here is that CNI must be installed
indepently but still enabled in the chart for it to be used.

Not installing the CNI chart or manifest while enabling CNI
will result in sidecar injector failures.
