The loadLanguageFile hook is triggered when a language file is loaded. It
passes the file name and the language as arguments and does not expect a
return value.
string $name
The language file to be loaded (e.g. tl_content), without file extension.
string $currentLanguage
The language, usually the same as $GLOBALS['TL_LANGUAGE'] but the call to
\Contao\System::loadLanguageFile accepts a language parameter.
string $cacheKey
The internal cache key.
