What problem are you trying to solve?

Devbox plugins are great, however I would like to retrieve privately hosted Devbox plugins that are stored on my Gitlab server. If this is possible, it's not clear how to go about using the correct address & protocol. It doesn't appear Devbox even supports public facing plugins hosted on Gitlab.

What solution would you like?

Support the same protocols and syntax flakes currently do:

ie.:

{
  "packages:": [],
  "include:" [
     "git+ssh://git@gitlab.private-server.com/devbox-plugins/my-plugin?dir=test"
  ]
}

Alternatives you've considered

If this is not currently supported, I'm more than happy to create a PR with the feature.
