Atlantis

Looks like CI is failing <https://github.com/runatlantis/atlantis/pull/4592>

I think <@UFC8E63HA> was looking at this test recently?

```Run make build-service
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -v -o atlantis .
<http://github.com/runatlantis/atlantis|github.com/runatlantis/atlantis>
Error: Process completed with exit code 1.```

ah maybe it's the e2e test that's the problem
```atlantis % ./scripts/e2e.sh
./scripts/e2e.sh: line 7: ATLANTISBOT_GITHUB_USERNAME: unbound variable
./scripts/e2e.sh: line 18: NGROK_AUTH_TOKEN: unbound variable
atlantis % echo $?
1```

```+ ./ngrok config add-authtoken

ERROR:  accepts 1 arg(s), received 0```

looks liked `NGROK_AUTH_TOKEN` isn't being set in CI

yeah looks like that was changed recently in <https://github.com/runatlantis/atlantis/pull/4576>

it has nothing to do with CI, the e2e tests should not run on forks

this should be fixed now with this patch

```-    if: github.repository_owner == 'runatlantis'
+    if: github.event.pull_request.head.repo.fork == false```
