Routing: custom `param` option for `resources` DSL does not apply to statements in block

Checklist

[x] Upgrade Jets: Are you using the latest version of Jets? This allows Jets to fix issues fast. There's a jets upgrade command that makes this a simple task. There's also an Upgrading Guide: http://rubyonjets.com/docs/upgrading/
[x] Reproducibility: Are you reporting a bug others will be able to reproduce and not asking a question. If you're unsure or want to ask a question, do so on https://community.rubyonjets.com
[x] Code sample: Have you put together a code sample to reproduce the issue and make it available? Code samples help speed up fixes dramatically. If it's an easily reproducible issue, then code samples are not needed. If you're unsure, please include a code sample.

My Environment

Software	Version
Operating System	macOS 10.15.5 (Catalina)
Jets	2.3.16
Ruby	2.5.7, 2.5.8

Expected Behaviour

I expect the following route definition:

resources :test, only: [], param: :my_param do
  get :somewhere, on: :member
end

to produce the following routing table:

+----------------+------+-------------------------+-------------------+
|       As       | Verb |          Path           | Controller#action |
+----------------+------+-------------------------+-------------------+
| somewhere_test | GET  | test/:my_param/somewhere | test#somewhere    |
+----------------+------+-------------------------+-------------------+

Current Behavior

The above route definition produces:

+----------------+------+-------------------------+-------------------+
|       As       | Verb |          Path           | Controller#action |
+----------------+------+-------------------------+-------------------+
| somewhere_test | GET  | test/:test_id/somewhere | test#somewhere    |
+----------------+------+-------------------------+-------------------+

The path param is named :test_id instead of :my_param.

Step-by-step reproduction instructions

Create a new Jets project and overwrite config/routes.rb with the sample below.
bundle exec jets routes
Observe the incorrect route

Code Sample

# config/routes.rb
Jets.application.routes.draw do
  resources :test, param: :my_param, only: [] do
    get :somewhere, on: :member
  end
end

I'm happy to also provide a patch to spec/lib/jets/router_spec.rb to easily and quickly reproduce the problem.
