The explanation to setup auto completion of zsh with Oh-My-Zsh is correct, however the example code is incorrectly mentioned as `source <(kubectl completion zsh)`. This pull request updates it to `plugins=(kubectl)`
Also, if the kubernetes.list does not exist you will not be able to edit it, so adding touch and then add the line will prevent errors with installing via apt-get.
This commit adds a missing closing capture and puts "## Install kubectl" inside the relevant capture.
Note that the missing close was also missing before Hugo-migration, so the section ordering is still not the same as the Jekyll version of the site. But I think it is more corret.
Note that content outside the capture template blocks, is included as defined is this template:
