Add docs/modules/compose.md page for compose module

Indeed, it's on purpose as we do have a separate page in https://golang.testcontainers.org/features/docker_compose/.

But I think it would be a good idea to add it to the modules and reduce the number of corner cases across code generation. I'll do it in a separate PR. Thanks for pointing this out!
