Subject: [PATCH] Add user agent header for fetch latest commit

For some reason GitLab (or CloudFlare) respond with 403 Forbidden for
requests made using urllib. By setting the user agent we can complete
the requests successfully.

See https://gitlab.com/gitlab-org/gitlab/-/issues/219669 for the
corresponding issue in the GitLab issue tracker.
