- Upgraded `go.mod` to use Go 1.23 and updated module dependencies to latest versions
- Refactored code to align with API changes in Docker and related modules:
- Updated `ContainerListOptions` to `container.ListOptions` and related structs
- Replaced `types.ImageDeleteResponseItem` with `image.DeleteResponse` for compatibility
- Modified `ImagePullOptions` and `ContainerRemoveOptions` to updated package paths
Log based on registry known-poor support of HEAD in checking container
manifest.
Some private registries do not support HEAD (E.G. GitLab Container Registry).
With the current config, this log message is causing a notification to be
sent for each container hosted in a registry lacking HEAD support.
log.Debug or log.Warning for failed HTTP HEAD-check based on registry hostname
where HEAD-check is known to fail.
For Docker Hub, a failed HEAD leading to a "regular pull" may count against a
user's call-quota whereas other registry implementations do not support HEAD,
or whose container manifest may be in a different location.
