You mean package registry/repository? Besides GitHub Packages there are projects like jfrog artifactory (commercial). It supports php composer, npm, docker, ruby gems, maven… and custom layouts. Maven is mostly known in Java, I think, but also D’s package manager, dub, supports maven repositories. So there are definitely a few of them.
As for package managers, it’s probably difficult to bring a completely new solution, because each language has its own established infrastructure, that is often mature and well-documented; and it is almost impossible to compete with all of them. Nix allows to build packages from different languages, but it’s kind of difficult, requires know-how and workarounds to work with ruby, js, php packages.
