Permission denied when creating a stub model

[wvanheemstra]

When I run below command as per the threagile help documentation, it fails:

$ docker run --rm -it -v "$(pwd)":/app/work threagile/threagile -create-stub-model -output /app/work
panic: open /app/work/threagile-stub-model.yaml: permission denied
