pr-auditor: try using default GITHUB_TOKEN to set commit status on forks
Created by: bobheadxi
testing out forks again, wondering if the default GITHUB_TOKEN might be allowed to set commit statuses on forks. previous attempt to switch to using the run output did not work very well: https://github.com/sourcegraph/sourcegraph/pull/31946#issuecomment-1054550210
looks like it doesn't work :( even with the default token, https://github.com/sourcegraph/sourcegraph/runs/5488972911?check_suite_focus=true#step:4:31

The issue is setting commit statuses on PRs - the check does run (see check logs), but for whatever reason GitHub doesn't allow you to set the status on commits on forks
😬 You're only allowed to use the run output. This doesn't work for us because we use the pull request events so that we get the pull request payload in the event - subsequent pushes will look "green" when it is not. We can run on push, but that doesn't include the PR payload, necessitating extra API requests to perform the PR description check
