This is my first time contributing to this project. Don't hesitate to tell me if I'm missing something / doing something wrong.

Thanks for your contribution! Can you add a changelog fragment? Thanks.

You also need to add a new entry for sysctls to option_minimal_versions (line 2747). The required API version is apparently 1.40, and it has been added to Docker SDK for Python 6.0.0 according to docker/docker-py@58aa62b.

You also need to adjust the integration tests. You probably have to add sysctls: null to https://github.com/ansible-collections/community.docker/blob/main/tests/integration/targets/docker_swarm_service/vars/main.yml.

Thank you for the feedback, I made the requested changes

Thanks, looks good to me! If nobody objects, I'll merge this in ~a week.
