Two fixes for the [Prisma
guide](https://supabase.com/docs/guides/database/prisma):
- `StepHikeCompact.Code` marked its whole subtree `not-prose`, so the
labels and admonitions that steps interleave with their code samples
rendered at 16px with zero margins, flush against the samples and tab
bars. Dropping `not-prose` restores body typography and spacing;
back-to-back samples now get a gap too, since they have no prose between
them.
- The guide's three outer tab groups omitted `type`, so they fell back
to pill styling — the only pills among 395 `<Tabs>` in the content tree.
