A container action works on ubuntu runners. A team changes runs-on to windows-latest and the action no longer runs. What requirement should they check?

1. The action needs to rename Dockerfile to Dockerfile.windows and otherwise remain unchanged.
2. A Docker action supports every operating system that can run a JavaScript action.
3. Docker container actions require a Linux execution environment with Docker available.
4. The caller must replace the action input with a repository variable to select Linux.
