Change image tag/digest only

[bluebrown]

Currently, kobold updates the full image ref. This leads to the default registry being added to image for non fully qualified domain names. It would be better if only the tag / digest would be changed.

How would we like to do this?

So, currently, by default, we only support full image URIs like this...

image: test.azurecr.io/nginx # kobold: tag: latest; type: exact

Would something like the following work to support parts?

image:
  repository: ...
  tag: "1.0" # kobold: tag: ^1; type: semver; part: tag
  digest: "" # kobold: tag: ^1: type: semver; part: digest

aah this one. Yes I have though about that as well. Its not what this issue here is about but its definilty something that would make sense

The logic for this is here https://github.com/bluebrown/kobold/tree/main/krm in filter.go and comment.go. If you want to take a stab @rossigee
