Test jsonschema

Merge Request Description

This allows us to update the pipeline Runner back to using the 0.5 pipeline-runner. We are able to do this as Kenn found the issue in our code that was causing a failure with the newer version of jsonschema.

Merge Request BOE

Risk

If the jsonschema doesn't run as expected, we may have failing pipelines on the lint stage again.

Testing

Testing was done in Mario. Confirmed that the lint job fails if I use the 0.5 image, and succeeds with this image if I update the jsonschema.validate command as seen in the diff.
