Move Next.js patch to install script

[karlhorky]

We currently instruct students to patch Next.js to fix / add a few features to the app/ directory:

• Disable soft navigation on navigation and redirect [Bug] next/link is not calling the server for subsequent navigations on dynamic routes  vercel/next.js#42991 (comment)
• Add generic type parameter for NextResponse Accept generic type parameters for NextResponse vercel/next.js#45943 (comment)
• Allow Link[href] values pointing at GET Route Handlers [NEXT-764] GET Route Handlers not valid destinations with experimental.typedRoutes vercel/next.js#46742 (comment)

The goal will be to remove this patch as soon as possible, but it's unclear how long it will take for these fixes / new features to be implemented and accepted in Next.js.

For now, implement a patching system (using pnpm) within the ESLint config install script to apply the changes in the patch.
