Recently we learned that autobumper when searching for newer image version is in fact searching for latest tag. Once the image version with latest tag is found it will take the tag in format date-short_sha for the same version and update it's usages. Because buildkit-image-builder had a latest tag set on image version from 04.01.2024, that version was used to update usages.

I've set the latest tag to the newest version of the buildkit image. We need to test if this solved the problem. Additionally, we must confirm how latest tag is set on our images. This is important because image-builder doesn't set latest tag. Because we are using three different tools to build images in test-infra, we must make sure all images can be bumped by autobumper. See #9434
