`manage.py` commands user ownership

[aleprovencio]

First, sorry if this is intended behavior and not bug.

I've have created a new project with all default options, except for opting to use docker.

Everything works as the docs suggests, until I have to use a manage.py command that will create files, ex:
docker compose -f docker-compose.local.yml run --rm django python manage.py startapp test_app or even better, just manage startapp test_app

Files are created with root as the owner instead of my user. I'm aware of this old issue, but for now my wordaround is using -u dev-user to run manage commands.

Should this be mentioned in the docs or can you point me the correct approach?
