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.
A tab shortcode was using angle brackets even though the
contents were markdown. This caused a formatting issue.
This switches the tab to use the `%`-delimiter to properly
render the markdown.
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:
