Introduce conflicts earlier during editing of metadata #119
Description
Recent feedback and general feeling is that collaborators get a little bored whilst waiting for repository owners to complete the setup tasks for the repository and edit the metadata.
We could perhaps get all team members to add their details to the metadata data and make pull requests. This would introduce merge requests much earlier in the exercise and reduce overlap with the tests failing in CI.
After having seen the merge conflicts and how to resolve them they should then be able to resolve those that arise later in the task (reinforcement learning aspect).
