Add workflow with issue creation option to setup interview with option to create issue on separate repo

[CaroRob]

We use a separate, private repository for our issues.
I would like to be able to send the output of unexpected results to become issues in our private issues repository.
So when we set up testing for each repository, I would like the set up interview to ask for the repository I want to use.

In the ALKiln Setup interview, we would give the user the option to add the "create an issue" code to their workflow. If/when we do that, we could add the ability to send that issue to a different (private) repository.

MVP: Document how to create an issue on a separate repository

• Tasks:

1. Research workflow to create issues on a separate repo from the action repo
2. Same, but the separate repo is a private one
3. Add that code to the documentation
4. Add the option in the setup interview to add issue-creation code to the workflow file
5. Add the option to send it to a separate repository (private or public)
