chore(deps): update ghcr.io/renovatebot/renovate docker tag to v44.106.0

- Baut und veroeffentlicht bei Aenderungen auf nightly zusaetzlich zu den
  Debian/RPM/Arch-Paketen ein Docker-Container-Image, analog zu den
  Testing-/Stable-Docker-Steps in testing.yaml/main.yaml.
- Tags: nightly, <VERSION>-nightly, <VERSION>-nightly.<BUILD_NUMBER>,
  nightly-<BUILD_NUMBER>.
- 'Dockerfile' zum Change-Filter der nightly.yaml ergaenzt, damit reine
  Dockerfile-Aenderungen ebenfalls einen Nightly-Build ausloesen.
