Describe the bug
Bumped up K9s from 0.9.3 to 0.11.3 and the plugin for ksniff does not work any longer! :-(
When I try to launch the ksniff plugin with K9s 0.11.3, I got:

Boom!! runtime error: index out of range [1] with length 1.

My ~/.k9s/plugin.yml looks like this

plugin.yml

plugin:
ksniff:
shortCut: Shift-S
description: "Sniff"
scopes:
- containers
command: kubectl
background: true
args:
- sniff
- $POD
- -n
- $NAMESPACE
- -c
- $COL0

To Reproduce
Steps to reproduce the behavior:

1. Setup the ~/.k9s/plugin.yml according to above
2. Launch k9s version 0.11.3
3. Goto the Containers view and click "Shift+S"
4. Boom!! runtime error: index out of range [1] with length 1.

Expected behavior
Expected that Wireshark should open as releases up until 0.9.3
