[Bug]: (v7) typegen doesn't take into account `appDirectory` config setting

[vsnig]

What version of React Router are you using?

7.0.0-pre.1

Steps to Reproduce

This repo is a clone of the sample app (npx degit remix-run/react-router/templates/basic#dev my-app) with {appDirectory: './app/website'} config setting and files that previously were in app moved to app/website

> git clone https://github.com/vsnig/rr-v7-typegen
> npm i
> npm run typecheck

Expected Behavior

Path to generated routes types should be .react-router/types/app/website/routes

Actual Behavior

Path to generated routes types is .react-router/types/app/routes Not taking into account appDirectory config setting and making them impossible (as far as I can see) to import
