Probot 14 changed its default webhook path from "/" (Probot 7) to
"/api/github/webhooks", but the GitHub App still POSTs to
https://kredits-github.kosmos.org/. Every delivery returned 404, so the
app never processed pull_request events and never created the Kredits
check run. Serve "/" again via WEBHOOK_PATH.
Chef's systemd_unit :create only runs daemon-reload and never restarts a
running unit, so the env change above would not have taken effect until
the next repo change or reboot. Manage the unit with :create/:enable and
restart it from a service resource that subscribes to unit changes.
Apply the same fix to the kosmos-hubot bot resource.
