Build out GitHub Actions for the dPopp team

Do we need more information then just ensuring github actions is being utilized on dPopp repos?

Start by reviewing the dPopp repositories and documenting which GitHub Actions workflows already exist. Clarify what “being utilized” should mean and which additional automation is required before making changes. Done should be defined as an agreed set of GitHub Actions workflows across the relevant dPopp repositories.
