Fix resource action method options

Description

The docs say that you can set the method on a resource action and the default is 'get' no matter the resource. Setting the method does not change the method used, and the default is different for every resource action type. The only way to change the method is through the resource definition options (create, update, delete, ...).

Requirements

• The request method should not be allowed to be set on resource actions.
• The docs should either say the request method used for the action or not state anything about the method.
