RemixImage loader error: Cannot read properties of undefined (reading 'fetch')

`context.ASSETS.fetch` is undefined at runtime

Using the cloudflare-pages example I am running into issues with the context.ASSETS.fetch(...) fetcher not being defined.

I think I have narrowed it down to entry.server.tsx having both remixContext & loadContext,

  remixContext: EntryContext,
  loadContext: AppLoadContext,

where only remixContext is passed into <RemixServer ... /> and appears that loadContext has the fetcher and it not used in this iteration of remix + cloudfare-pages.

I think I've searched as deep as I can on this issue, and it appears that either remix and/or @remix-run/cloudflare projects have made changes to context that the documentation/examples in the remix-image repo might not be up-to-date with.

Your Example Website or App

Steps to Reproduce the Bug or Issue

This is a runtime issue with the context, check the repo link for the code.

Expected behavior

The fetcher should be available at runtime, wondering if I need to combine both contexts to be able to use them in the image loader.
