Fix the build + make sure that future breakage does not go unnoticed
Created by: hartwork
Hi!
This pull request:
- (Sits on top of #47 (for an actual chance on a green build) but I'm happy to rebase it off of it in case #47 gets merged first.)
- Fixes the build
- Adds essential CI so we'll notice if the build ever breaks again (see https://github.com/hartwork/cosinnus-devops/actions for the current build log)
- Configures GitHub Dependabot to keep the added GitHub Action up to date
What do you think?
Best, Sebastian
