## Overview

I added some logic to add the running user to the `all-contributors`
list (according to the authenticated GitHub CLI account).
At first, I tried only to use the owner variable that the user prompted,
but it failed the tests, where a fabricated owner name was provided; if
you prefer to only use the provided owner name without reaching out to
gh CLI, we might need to adjust the tests a little bit.
