{{- /*
  since shortcode

  Renders a small badge linking to the release where a feature was introduced.

  The version is taken from, in order of precedence:
    - the first positional argument:  since "2.17.0"
    - the named "version" argument:   since version="2.17.0"
    - the page's "since" front matter: since = "2.17.0"

  The link target is built from the printf format string in
  params.ananke.shortcodes.since.url, which receives the version as its only
  argument (default: the Ananke releases page).
