[Cookbook][Routing] & [Book][Routing] update "_method" to "methods"

[X13454]

Hello,

Looking at English version of http://symfony.com/doc/master/book/routing.html#adding-http-method-requirements, (YAML tab) we have:

# app/config/routing.yml
contact:
    path:     /contact
    defaults: { _controller: AppBundle:Main:contact }
    methods:  [GET]

contact_process:
    path:     /contact
    defaults: { _controller: AppBundle:Main:processContact }
    methods:  [POST]

whereas in http://symfony.com/fr/doc/master/cookbook/routing/method_parameters.htm and http://symfony.com/fr/doc/master/book/routing.html#ajouter-des-conditions-requises-pour-la-methode-httpl, we have this semantic:

        _method:  GET
        _method:  PUT
       ...

It seems that the [methods] option was introduced in version 2.2 http://symfony.com/doc/2.2/book/routing.html#adding-http-method-requirements.

Should the http://symfony.com/fr/doc/master/cookbook/routing/method_parameters.html and http://symfony.com/fr/doc/master/book/routing.html#ajouter-des-conditions-requises-pour-la-methode-http be updated with the latest option, for consistency sake?

Kind regards
