Missing colordiff as external diff for kubectl #66

Hi,

It would be nice if this image would contain the colordiff tool in order to be used as an external diff for the kubectl command.

Best regards.

This image has helm-diff (latest commit) already.

Second, I went through its homepage (please confirm we are talking about the same tool): https://www.colordiff.org/

it needs perl, which I prefer Golang binary to keep the image size small.

helm-diff is for helm chart. When the kubernetes resources I want to apply is not managed by an helm chart, I use kubectl and I always have in my CIs a diff stage before applying the changes to see what would be applied. kubectl have a diff command but does not manage colors in diff. I use the KUBECTL_EXTERNAL_DIFF="colordiff -N -u" environment variable with colordiff https://www.colordiff.org/ to have a better output.
