Task/add explicit @prisma/config import

It's used in `.config/prisma.ts` and is coincidentally available for the
`postinstall` to run correctly (already present in the lockfile).

However, some tools (that are not npm) might complain that it should
either be explicit or hoisted with an `.npmrc` flag.
