Kaniko v0.6 uncompatible with https://github.com/lfs269/tekton-ci.git (sha:6865b8ee)

For those who want to try the last Kaniko version from Tekton Hub (v0.6) note:

• that the value type for EXTRA_ARGS changed to an array
• other changes listed in the changelog makes the last task 'verify-digest' breaking the pipeline (my removing this task I was able to publish to the docker registry). Bizarrely, I had no longer any log from tekton
  

Note I was able to use the last git clone taskk from Tekton Hub and complete the section by using the kaniko 0.3 indicated in the lab guide.

Thanks

Béatrice
