Add docs for switchLocale in view

[ntvsx193]

Issue make from https://forum.adonisjs.com/t/antl-view-with-user-locale/462/6

I don't think this has to be the part of docs. The antl object is shared with view and that means all methods can be called inside view and not only switchLocale.

Also I will never never views to mutate state, this is literally the worst way to do something. One should call antl.switchLocale inside controller and then render the view.

Can you write example code for usage with switchLocale for view in controller?

[thetutlage]

controllerMethod ({ antl, view }) {
  antl.switchLocale('fr')
  return view.render('some-view')
}

NOTE: The antl instance is shared with controller and the view you will render from that controller.

Wow! It is great! I think otherwise :)
I am add this to docs

[thetutlage]

I will not, since one thing leads to other. If method a is documented, then why not b, which will end up in duplicated docs everywhere.

Okay, i'm found now in docs

http://adonisjs.com/docs/4.0/internationalization#_context_instance

However, you can also make use of the antl object, which is passed to all route handlers like request and response.

But it's not explicitly indicated.
