Update TWiN script (#1047)

* Retrieves previous 7 days of contributions by default
* Checks all repos under the `nushell` user - Reports against the most
recent (up to 30, and we currently only have 26) with updates.
* Uses the GitHub client to authenticate if available, with fallback to
a token, then username/password
* Cleans up a lot of the URL building using more recent Nushell
commands.
