Add resource name to the ArgumentError that's raised when invalid :only or :except options are given to #resource or #resources

This makes it easier to locate the source of the problem, especially for routes drawn by gems.

Before:

    :only and :except must include only [:index, :create, :new, :show, :update, :destroy, :edit], but also included [:foo, :bar]

After:

    Route `resources :products` - :only and :except must include only [:index, :create, :new, :show, :update, :destroy, :edit], but also included [:foo, :bar]

Fixes rails#54134
