Is your feature request related to a problem? Please describe.

My project is failing on netlify because I'm using middlewares, which are now stable in react-router. Here is the log:

Sep 24, 08:01:12 AM: dead8f89 ERROR  Error: Invalid `context` value provided to `handleRequest`. When middleware is enabled you must return an instance of `RouterContextProvider` from your `getLoadContext` function.
    at requestHandler (/var/task/node_modules/react-router/dist/development/index.js:1145:21)
    at file:///var/task/node_modules/@netlify/vite-plugin-react-router/dist/index.mjs:14:30
    at async WC (file:///var/task/___netlify-bootstrap.mjs:7:85589)

    at async Runtime.handleOnceStreaming (file:///var/runtime/index.mjs:1239:26)

Describe the solution you'd like

It seems that the problem is fairly easy to fix, as it is documented (see for example the vercel related issue: vercel/vercel#13327).
I believe the code at https://github.com/netlify/remix-compute/blob/main/packages/remix-adapter/src/vite/plugin.ts#L26 needs attention. I don't know about the classic-compiler flavor.

Describe alternatives you've considered

I'm considering switching to a custom request handler to circumvent the issue.

Additional context

It's gonna be standard in the next major, so implementing that now is gonna be helpful to be ahead of the curve.
