Use OctokitApp to display repository list

This setup iterates over all installations of the GitHub app and displays their repositories in the previously made table. Iterating over multiple installations rather than specifying it explicitly will allow us to support repositories we manage in other organisations by getting them to install Towtruck as a GitHub app in their organisation settings and granting access to the repositories that we maintain for them.
