Add docformatter to the pipeline's pipeline

Background

We need to add docformatter to the pipeline's CD pipeline. To do this, we'll need to add a new job to the linting stage and follow the recommendations from #815 (closed). We should also run the formatter against everything in stages and ironbank.

Acceptance Criteria

• docformatter job is added to the pipeline's pipeline
• all docstrings are reformatted where needed

Definition of Done

• docformatter passes in the pipeline's pipeline
