Use GitHub app instead of OAuth app for GitHub auth in CLI

[tedim52]

Background & motivation

OAuth apps require repo scope to read repos. The perms on that scope are too permissive to be comfortable for users.

Desired behaviour

Instead we use a GitHub app: https://docs.github.com/en/apps/creating-github-apps/about-creating-github-apps/deciding-when-to-build-a-github-app#github-apps-offer-enhanced-security

That allows users to select the perms they want.

How important is this to you?

Critical; Kurtosis is unusable for me without it.

What area of the product does this pertain to?

CLI: the Command Line Interface
