CodeLens support for rails routes with constraints

[jukra]

Thanks for your great work on this add-on!

I noticed that I don't see the Rails routes in controllers (https://shopify.github.io/ruby-lsp/rails-add-on.html#go-to-controller-action-route) due to the routes being inside constraints (https://guides.rubyonrails.org/routing.html#request-based-constraints). If I move the route outside of the constraint and reindex, the route shows up in the CodeLens. Is it possible to extend the support for these?

I think it fails because of not having the subdomain requirement present here:
https://github.com/Shopify/ruby-lsp-rails/blob/main/lib/ruby_lsp/ruby_lsp_rails/server.rb#L193-L198

For example one my routes has these

 @defaults={:subdomain=>"app", :controller=>"health", :action=>"index"},

which would not match when requirements just have the controller and action present and comparing the full hash (route.requirements == requirements)

::Rails.application.routes.from_requirements({ controller: "health", action: "index" })
=> nil

::Rails.application.routes.from_requirements({ controller: "health", action: "index", subdomain: "app" })
=> 
#<ActionDispatch::Journey::Route:0x0000000133e56e18

If the full hash comparison does not give any results, could there be a fallback that just checks with controller and action or something like that?

::Rails.application.routes.routes.find { |route| route.requirements[:controller] == requirements.fetch(:controller) && route.requirements[:action] == requirements.fetch(:action) }

Or is there a way to get the subdomain context somehow in the params?
