fix(antergos-minimal): fix malformed YAML in minimal-info.conf, copy to online/offline module dirs

- YAML document separator '---' was glued to 'qmlSearch' key, causing
  the notesqml module to fall back to default example release notes
- Copied the config to calamares-online/modules/ and
  calamares-offline/modules/ so both modes can find it
