Try to warm all images and warn about errors (#1653)

When providing multiple images to warm, the warmer stops at the first error.
There are use cases however where an image is provided to the warmer which does not yet exist on purpose (e.g. CI/CD latest image only created at first release).
Thus we want to try all given images and only error if none of them work.
