Subject: [PATCH 1/2] Set GH_REPO for the `gh` CLI tool

Unless executed in a git repository, `gh` no longer seems to get
information about the current repo where it's executing, which leads to
failures like the one in #889. A simple solution is to set the
`$GH_TOKEN` environment variable, which `gh` uses if it's defined.
