We need to make some minor updates to our tekton files per https://github.com/konflux-ci/build-definitions/blob/main/task/buildah/0.2/MIGRATION.md. Specifically - 

• Removes the BASE_IMAGES_DIGESTS result. Please remove all the references to this result from your pipeline.
  • Base images and their digests can be found in the SBOM for the output image.
• No longer writes the base_images_from_dockerfile file into the source workspace.
• Removes the BUILDER_IMAGE and DOCKER_AUTH params. Neither one did anything in the later releases of version 0.1. Please stop passing these params to the buildah task if you used to do so with version 0.1.
