* Use | relLangURL for the base urlº
This way, when you click on the header it maintains you in the same language you previously selected.
* Use .Site.Home.RelPermalink as proposed by @regisphilibert
Using the `{{ .URL }}` token results in a warning:
WARN 2019/10/13 15:12:12 Page's .URL is deprecated and will be removed in a
future release. Use .Permalink or .RelPermalink. If what you want is the
front matter URL value, use .Params.url.
