Create a list from code coverage

@samuelpmish would like a easily readable list of what changed in the code coverage. Codecov does provide a webpage but it requires several clicks to really see what changed. A simple list would be more useful. This could also be added as a build artifact to the `Check_Code coverage` CI job.

Start by locating the `Check_Code coverage` CI job and reviewing how Codecov currently reports coverage. Define the readable changed-coverage list and add it as a build artifact; done means the job produces that artifact alongside its existing coverage result.
