Returns the value associated with key under group_name
translated in the given locale if available. If locale is
null then the current locale is assumed.
If locale is to be non-null, or if the current locale will change over
the lifetime of the #GKeyFile, it must be loaded with
G_KEY_FILE_KEEP_TRANSLATIONS in order to load strings for all locales.
If key cannot be found then null is returned and error is set
to G_KEY_FILE_ERROR_KEY_NOT_FOUND. If the value associated
with key cannot be interpreted or no suitable translation can
be found then the untranslated value is returned.
