Subject: [PATCH] `import-in-hugo.sh` renders _only_ current _or_ archived

* The artifact-id and the version of the project are _always_ added to the
  specified base-path.
* If a *current* version is copied the version is dropped from the path
  that is added as `url` to front-matter.
* If a *archived* version is copied, the path of the current version is
  added as `params.canonical` to front-matter.
