fix(ci): remove container directive for dockerized runner compatibility

Gitea act_runner in Docker mode maps the runs-on label to a container
image via its config. The container: block conflicts with this by
attempting to create a nested container. Remove it so the runner's
own docker://ubuntu:24.04 mapping is used directly.
