Update @prisma/internals to v5.8.1

[DanielleHuisman]

The current version of @prisma/internals depends on an insecure version of undici. By updating @prisma/internals this issue is resolved.

And I have a question: what is the maintenance status of this project? I see there are quite a few outdated dependencies and open PRs. Do you need any help?
