Next Auth basePath repo

Changes made (based on next and nextauth docs, see commit for details):

• NEXTAUTH_URL is http://localhost:3000/custom-route/api/auth
• SessionProvider has basePath set
• next.config.js has basePath

Environment is already included.

npm run dev

Visit http://localhost:3000/custom-route.

Pages will render as before.

BUT... can't Sign In (will get HTTP error)

Change to v4.18.1 to see it work:

npm i next-auth@v4.18.1
npm run dev
