[html] Issue: Default <details> heading should be localized marked as i18n

chaals has just labeled an issue for https://github.com/w3c/html as 
"i18n":

== Default <details> heading should be localized ==
> If there is no child summary element, the user agent should provide 
its own legend (e.g. "Details").

In practice, UAs have implemented the default title of "Details", 
which does not seem to change depending on the specified language 
[[demo]](http://dabblet.com/gist/e0be732fbc828ebb5ea494edef1a5d4f). I 
think it should be explicitly mentioned that the default title should 
be localized.
