I've repleced the checks with the content provided by the onliner here: https://github.com/simonbaird/konflux-pipeline-patcher/blob/main/specific-one-liners.md#sast-unicode-and-shell-check-tasks

Currenlty fails because of:

Results:
✕ [Violation] tasks.required_tasks_found
  ImageRef: quay.io/redhat-user-workloads/devfiles-tenant/registry-viewer-main@sha256:b686e21d9f8ec73b94182ae02376b4403eaa3b9e42c04a4843204e46a4c1f56f
  Reason: One of "sast-unicode-check", "sast-unicode-check-oci-ta" tasks is missing
  Title: All required tasks were included in the pipeline
  Description: Ensure that the set of required tasks are included in the PipelineRun attestation. To exclude this rule add one or
  more of "tasks.required_tasks_found:sast-unicode-check", "tasks.required_tasks_found:sast-unicode-check-oci-ta" to the `exclude`
  section of the policy configuration.
  Solution: Make sure all required tasks are in the build pipeline. The required task list is contained as
  xref:ec-cli:ROOT:configuration.adoc#_data_sources[data] under the key 'required-tasks'.

My guess is we need first to merge devfile-web
