Fix finding bluechi-image container

We have been using `filters` parameter for `images.list()` in podman-py
to search for bluechi-image container. But podman-py 5.3 changed the
behaviour of `filters` paramater as a part of
containers/podman-py#457 , so we need to use
`name` parameter for searching.
