fix: make service_registries fields optional @olafbado (#300)

## what

Updated the service_registries variable to make port, container_name, and container_port optional.

why

• The current implementation forces users to set all three fields, which leads to invalid configurations in ECS
• This change aligns the module with the actual ECS API behavior.
• It unblocks valid use cases, such as using service discovery in Elixir/Erlang clusters running on ECS Fargate
