Update all repositories still using `ubuntu-20.04` for workflows

We still have plenty of repositories still using `ubuntu-20.04` in their workflows: https://github.com/search?q=org%3Ainveniosoftware+ubuntu-20.04+language%3AYAML+path%3A.github&type=code

We have until April 1, 2025 until the runner image is unsupported (see email notification below). We should for each repository:

- update them to use the reusable workflows from this repository
- if the above is not possible, explicitly update the workflow to `ubuntu-24.04`
