Should publish-chartpress-images force-build and force-push?

[leafty]

By default, chartpress will not build and push images if it finds that the tag already exists. However this is not the correct behavior for publish-chartpress-images which runs on tagged git refs. The image should always be built and pushed by these actions.

The potential problem which can arise is that chartpress builds an image with the corresponding tag from another action (e.g. PR deployments) but not with the correct repository contents (chartpress can sometimes get version numbers wrong with merge git commits). This is most likely a rare issue, but still possible as wrong tags from chartpress happen from time to time.
