feat(plugins): bump prisma to 7.8.0

prisma 7 no longer allows a url property in schema-file datasource
blocks, while prisma 5/6 require it, so a separate basic_7 fixture
covers 7.x and the original fixture keeps covering the 5.x snapshots.

7.8.0 is the newest release passing the 30-day stability gate
(published 2026-04-22) with no known security advisories.
