Adds code coverage and reporting of unit tests.

@szschaler as demo'd in this mornings meeting code coverage is reported in the summary github ci worflow e.g. https://github.com/mdenet/educationplatform/actions/runs/8013383834

There wasn't a huge selection of GiHub actions for reporting code coverage nicely that worked, so went with adding markdown to the workflow action summary using action - https://github.com/danielpalme/ReportGenerator.

Do we want to improve this report e.g. publishing a detailed html report with history as a webpage or do you think the simple output is sufficient?

Another option that offers the most comprehensive and visually appealing report is https://about.codecov.io/ that provide a GitHub action, however, it is an external service so it sends the results to them. It is free for opensource projects, not sure if that applies to us.

I think that simple output is enough for now.

I notice the following annotation:

Node.js 16 actions are deprecated. Please update the following actions to use Node.js 20: actions/checkout@v3, actions/setup-node@v3, actions/setup-dotnet@v3. For more information see: https://github.blog/changelog/2023-09-22-github-actions-transitioning-from-node-16-to-node-20/.

Is this something we can fix?

[barnettwilliam]

Yes updating the actions/checkout, actions/setup-dotnet in my test repo fixes this so I'll update here.

Looking good.
