GET routes for Generic Actions do not assume the arguments as query params

[diogomrts]

Describe the bug
When defining a GET route for a generic action, if we define optional arguments they are not accepted as query params.
In the open_api spec they are shown as part of the request body inside data but this also does not work unless we change the Route to POST.

To Reproduce

base_route "/operational-settings", Core.OperationalSetting do
  route(:get, "/:configuration_key", :get)
end

 action :get, :struct do
  constraints instance_of: Type.OperationalSettingValue

  argument :configuration_key, :string, allow_nil?: false
  argument :campaign_id, :string, allow_nil?: true

  run fn input, context ->
    get_setting(input.arguments, context.actor)
  end
end

Expected behavior
In the example above the mandatory path param configuration_key works as expected but the campaign_id is not accepted as query_param.

All arguments that are not in the route should be lifted to the query parameters
