sample-next-auth-pages does not build

[leggetter]

Creating an issue to track a few problems I've found with the app:

• xata:init in package.json refers to a --schema=schema.template.json when it should be --schema=schema-template.json. Hyphen not period.
• The app uses getServerSession, which requires the req param to be a NextApiRequest, but the req is a standard Request.
• References to import { XataClient } from '~/lib/xata.codegen' should be updated to ~/shared/xata.codegen
