[ci skip] Add `Translating Rails Guides` to contributing_to_ruby_on_rails

Docrails is private now (6cb1b6724c313c608cf4063fc22886faa19df9be),
anyone who does not have access right to docrails can't read
"Translating Rails Guides" in wiki of docrails.
To prevent someone from giving up to translate, publish them on Rails Guide.

+Translating Rails Guides
+------------------------
+
+We are happy to have people volunteer to translate the Rails guides into their own language.
+If you want to translate the Rails guides in your own language, follows these steps:
+
+* Fork the project (rails/rails).
+* Add a source folder for your own language, for example: *guides/source/it-IT* for Italian.
+* Copy the contents of *guides/source* into your own language directory and translate them.
+* Do NOT translate the HTML files, as they are automatically generated.
+
+To generate the guides in HTML format cd into the *guides* direcotry then run (eg. for it-IT):
+
+```bash
+$ bundle install
+$ bundle exec rake guides:generate:html GUIDES_LANGUAGE=it-IT
+```
+
+This will generate the guides in an *output* directory.
+
+NOTE: The instructions are for Rails > 4. The Redcarpet Gem doesn't work with JRuby.
+
