One click package adding logic in the package list

[ruben-arts]

We've already added this button to the package lists:

We would like to hook this up to automatically create a PR on the relevant RoboStack distro GitHub repo.

Some ideas on how to do this:

1. Start a seperate server that can handle a GitHub App and let the user login to create a PR in their name. ( Departure from the serverless github pages we have right now)
2. Simply create a "Create Issue" link with prefilled description that could be picked up by a GitHub bot. (PR will not be in the user's name).
3. Point directly to the "Edit file" button of the relevant vinca.yaml (More complex for new people)

Input, ideas or contributions related to this are welcome!
