Subject: [PATCH] ci(release): upgrade v*.next.forgejo.org when the release is
 ready

The https://v$major.next.forgejo.org instances are polling for new
releases with a cron job every hour. This is not only a waste of
resources because there is nothing most of the time, it also imposes a
delay of maximum one hour when there is a new release.

When the release is published, notify the corresponding instance that
an upgrade is ready. In the request will 404 but leave a trace in the
logs which can trigger an upgrade script if wakeup-on-logs is
configured accordingly.

  GET https://v$major.next.forgejo.org/.well-known/wakeup-on-logs/forgejo-v$major

* v8 - a daemon watching on the web server logs was installed for
  https://v8.next.forgejo.org and will perform the upgrade.
* v7 - nothing will happen for https://v7.next.forgejo.org because
  it still relies on the hourly cron job.
* v1.21 - nothing will happen because https://v1.next.forgejo.org does
  not exist.
