Gather trainee workshop response insights

## Problem

On a Saturday, trainees will do workshops to develop their existing knowledge or learn new skills. Trainees submit responses to code problems or questions in a PR raised against the source repo. We need to summarise the responses in each repo and then collate this info so we can address the following questions:

- What are the most common misconceptions in this module?
- Are the workshops too long? ( supposing they're 1 hour long )
- Are the workshops too difficult?
- Which trainees are really struggling with the concepts in a given week? Is this a cause for concern?
