fix(example): Fix Prisma example (#8046)

Fix missing dependency `tsup` and incorrect import path of the
`database` package of the `with-prisma` example.

I was boostrapping an app using the prisma example and ran into some
errors mostly likely caused by some minor missing pieces in the previous
update #6571. This patch should fix
them.
