Make action container tests resolve container IP on Docker Engine v29+

[dorbae]

Description

ActionContainer.withContainer discovers a freshly started action container's IP with
docker inspect --format '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}'. Because the top-level network properties of NetworkSettings were removed in Docker Engine v29.0.0 (API v1.52).

range is used rather than hard-coding .Networks.bridge.IPAddress so the lookup does not assume a
network name. Containers created by createContainer() are started without --network and therefore
join exactly one network, so the range yields a single address.
