Renovate: Also check other repositories

- openvpn3 already has a renovate config which is
  usually handled by a differente renovate instance,
  but it is still useful to get PR builds for this in
  GitHub to verify the GHA updates directly.
- openvpn doesn't have renovate, yet, so we need to do
  onboarding first. See
  https://gerrit.openvpn.net/c/openvpn/+/722
