Local OCI cache not updated if same tag on remote registry is updated

[armas-mk]

If the packer machine already has pulled eg.: ocr-registry/macos-14:main and has it cached locally, it won't pull latest changes when i use the same image as dependency (using the OCI url) on another packer template despite SHA being different for the same tag on the registry vs whats stored locally.

I have to prune/delete the cache to make it pull the latest changes for the packer template thats dependent on that image:tag.

I reckon adding a pull step before cloning would solve this?
