Cookieplone generates invalid git repository url

[wesleybl]

In the frontend addon for example, in package.json, the following is generated:

  "repository": {
    "type": "git",
    "url": "git@github.com:collective/volto-add-on"
  },

The url: git@github.com:collective/volto-add-on is not valid. This causes problems, for example, when submitting a project to Dendency Track. I'm getting the error:

{
  "status": 400,
  "title": "The uploaded BOM is invalid",
  "detail": "Schema validation failed",
  "errors": [
    "cvc-datatype-valid.1.2.1: 'git@github.com:collective/volto-add-on' is not a valid value for 'anyURI'.",
    "cvc-type.3.1.3: The value 'git@github.com:collective/volto-add-on' of element 'url' is not valid."
  ]
}

To fix, the url must be in the format:

"url": "git+https://github.com/collective/volto-add-on.git"
