Download repositories from vcs sources

[mc0e]

I'd like to be able to install extensions from repositories without the need for a zip file. I imagine that composer would provide most of the required tooling if civicrm-extension were to use it?

I.e. I'd like to be able to do something like this:

{

    "extra": {

        "civicrm": {
            "extensions_install_path": "./web/sites/default/civicrm/extensions/contrib",
            "extensions": {
                "org.civicrm.lab.ckeditor5": {
                    "type": "vcs",
                    "url": "https://lab.civicrm.org/extensions/ckeditor5"
                }
            }
        },
   }

}

I've found the zip file for this particular extension, but I still think this would be a worthwhile feature.
