Issue reference

Fix #[issue number]

I don't use the devcontainer, but adding curl looks sensible to me.

I'm pretty sure nobody uses devcontainers seriously since the "make test" does not really work. But since you are not providing a flake.nix getting a dev environment running is just pain I'm not willing to do for some fixes ;) ....

@poelzi What specific challenges did you face? For me, this works fine:

make clean
make dev
make test 

Perhaps you didn't set the GITHUB_TOKEN env var? (No special permissions needed - it's a limitation of the gh CLI that doesn't allow downloads from public repos without a token set)
