Drop the explicit version requirements for web-console

Between major versions 2 and 3, we hit a bug. It's fixed in version 3,
however, the explicit 2.x requirement of `~> '2.0'` will prevent people
from getting the fix with `bundle update` and they would have to
explicitly set the constraint to `~> '3.0'`.

For more information see: rails/web-console#178.

I propose we drop the explicit version constraints in the Gemfile. Web
Console has been relatively stable for the past couple of years, and I
don't anticipate any major alterations, like we saw between major
versions 1 and 2.

Remove incorrect Rack documentation example

`Sprockets` does not respond to the call method, so I changed the

Prevent not-intended loading of `ActionDispatch::IntegrationTest`

After 9d378747 `ActionDispatch::IntegrationTest`
class is loaded and defined in all Rails environments, not only test but also
production. This is not-intended loading of a class which is only used in
test environment.
To prevent not-intended loading, add `ActiveSupport.run_load_hooks` to
`ActionDispatch::IntegrationTest` with `action_dispatch_integration_test` name
and use it in `ActionMailer`.

It's probably obvious to most, but clarify that `:helper_method` will make both
of these methods available to the view.

make attributes API  example to work [ci skip]

There is a need to pass the keyword arguments to `attribute` method.

Since we are using `datetime` in migration, better to use `datetime` is I think that confusion is less.

In the latest security releases render with a trailing slash no more call

Also add a note about the security implications of using it with user
parameters.
