Second arg for 'options for select' works in Rails 5

[dare05]

Here:

http://guides.rubyonrails.org/form_helpers.html

it writes:

The second argument to options_for_select must be exactly equal to the desired internal value. In particular if the value is the integer 2 you cannot pass "2" to options_for_select - you must pass 2. Be aware of values extracted from the params hash as they are all strings.

However, I tried doing exactly this in Rails 5 and it worked. So you might want to remove this or specify it applies for older versions of Rails.

This tip in the guides does date from 2009 (the birth of Rails guides?).
Perhaps we handle these better now?

@dare05 Would you be able to submit a PR to update the docs? Thanks!

Closing as there's no actionable bug here. Feel free to open a PR removing that warning if you wish, but it's not hurting anything if not.
