environments outside of sovereign-workplace git-repo

i like to use this repo as an source without the need to fork - by the following options:

• helmfiles option in my own helmfile.yaml with the git+http annotation
• in my repo i would like to use your repo as an git submodule

---

current this is blocked by an issue in helmfile v0.155.1, see: https://github.com/helmfile/helmfile/issues/948

if needed i would like to offer a merge request
