Creating as a subtask as it's a bit involved.
So, tekton does not update the helm charts anymore (https://github.com/cdfoundation/tekton-helm-chart/blob/main/charts/tekton-pipeline/Chart.yaml), so the upgrade has to be done manually with embedded yaml files in builds-builder.
This might require us to upgrade builds-api dependencies too to match the newer version of tekton.
Also, we might want to move the images to harbor instead or re-uploading to docker-registry.
