test: Valkey test improvements for testcontainers (#1280)

* test: testcontainers improvements

Use the endpoint feature to get the connection URL for the container.

There are cases where localhost is not the correct one, for example when DOCKER_HOST is set to another machine.

Also, don't specify the external port for the mapping so a random unused port is used, in cases when there is already Valkey/Redis running as a container and port mapped externally on 6379.

* also remove this hack, doesn't seem necessary.
