I get failures on the [deptrac](https://gitlab.com/rva-vzw/dikdikdik/-/jobs/1920837413)-job on gitlab-ci. I use the [ohartl/deptrac](https://hub.docker.com/r/ohartl/deptrac)-container for this job. I guess the container runs php 8.1, but the version of deptrac in the container doesn't support php 8.1 yet. Not sure though; I'll have to look into this. For the time being, I'll allow the deptrac job to fail.
