Hugo: Expose DefaultContentLanguage in Site variables

[EpicEric]

Currently, there's no way to get the default language of the site (other than assuming it has the smallest weight in the list of AllTranslations, with some caveats). This variable would be useful for creating conditions, for example (in my case) to check if a localized documentation is up-to-date with the original page.

[regisphilibert]

Though not very intuitive, .Sites.First.Language will give you what you're looking for (.Sites.First.Language.Lang returns the language code)

[EpicEric]

Is there any documentation for .Sites.First or .Sites? I can't seem to find it in Hugo Docs.
