Support for toolbox integration

[LecrisUT]

Some background, I am trying to develop a toolbox and I have developed a lot of tools to create native-like documentations. I want to split that code off to a separate toolbox and only use it for packaging the toolbox and creating releases. I am currently using the matlab github action for automatically packaging the toolbox and post them as a release.

So the feature request here is to allow setup-matlab to specify toolboxes (from matlab central, github etc.) that would be automatically pulled in and added to the matlab path.

Thanks for the feature request! I like the idea and there is work going on in this space. In particular, this sounds like a feature typically served by a package manager. The beginnings of that are starting to form with mpm. So keep an eye on mpm. setup-matlab would probably just expose whatever capability mpm decides to offer in this space.
