Remove `:api:` tag that has leaked on the doc directly [ci skip]

Currently `:api:` tag has leaked on the doc directly since RDoc doesn't
support `:api:` tag directive.

http://api.rubyonrails.org/v5.1/classes/AbstractController/Rendering.html

So `:api: private` doesn't work as expected. We are using `:nodoc:` for
the purpose.

Related #13989.
