In @.github/workflows/cicd.yml:
- Around line 65-66: The comment describing DOCKER_API_VERSION is misleading:
update the comment that currently reads "Lowest API version that GitHub runners
support" to clarify that DOCKER_API_VERSION: 1.52 is the maximum API version
Docker.DotNet is built against (Docker Engine v29 supports API 1.44–1.52), so
change the comment to state it's the maximum supported API version (or the API
version Docker.DotNet targets) to avoid implying it is the minimum; locate the
DOCKER_API_VERSION setting in the workflow and replace the comment accordingly.
