volume: fix WCOW volume mounts

Do not use the older `Volumes` field in the API; instead rely on
the more robust `Mounts`. For Linux containers, it seems that it's
fine to set both of these. For Windows containers (WCOW), however,
there appears to be a Moby bug that causes it to normalize the
anonymous (`Volumes`) variant to lowercase, which can result in
duplicative volume definitions and an error when trying to start
the container.

Fixes #9577.
