The Skaffold tool has a requirement for how image tags and repositories are passed into charts.
Some of our charts do not follow this spec, we should adjust them so that they do.

All charts can be found in https://github.com/wbstack/charts
The expected spec is something like this:

image:
  repository: ghcr.io/wbstack/mediawiki
  tag: "1.36-7.4-20211029-0"
  pullPolicy: IfNotPresent

And example change doing this for the mediawiki chart is https://github.com/wbstack/charts/commit/36e9f01a0c6455a2cd50a7e6465bf2bcc8b74b55
