Doesn't work with View Component >= 3.9.0

Attempting to upgrade the view_component gem and running into an issue.

Doing a bit of digging I found a change in VC 3.9 that might(?) be a source of the problem: ViewComponent/view_component#1950 specifically the changes to lib/view_component/base.rb:310.
It looks like when request is called it's calling the request method in bridgetown-routes/lib/bridgetown-routes/view_helpers.rb:22 which looks at view.resource&.roda_app. In my case the "view" in question appears to be the component instance.

If I add

def resource
  nil
end

to the BaseComponent everything boots and renders as normal. Not 100% sure if this is the correct work around it just works for me.

Versions

bridgetown: 1.3.4
bridgetown-view-component: 2.0
view_component: >= 3.9.0

config/initializers.rb

Bridgetown.configure do |config|
  init :"bridgetown-view-component" do
    ViewComponent::Base.config.view_component_path = "src/_components"
  end
  init :ssr
  init :"bridgetown-routes"
end

Let me know if there's any other information I can provide that might be helpful.

I'm inclined to just copy the patch over from citizensadvice/design-system#3362. Any further thoughts @DRBragg and @davidrapson?

[davidrapson]

Unfortunately we've hit a new error with view component 3.15+ which we're trialing a patch for here citizensadvice/design-system#3503

Not sure how robust that patch is as I'd sidestepped an issue with Bridgetown::ViewComponentHelpers being included which had a different error.

I think the direction of stubbing in a controller/request object is along the right lines as I think increasingly view component is relying on that being present, which is not the case in a bridgetown context, but still not convinced I've got the right angle on a patch.

I'd be happy to put together a reduced test case with the latest version if that would help.

TBH I haven't touched this is quite some time. If I have some free time in the next week or so I'll take another look at it but until I do I lack update to date enough knowledge to have an informed opinion
