refactor: only test prisma v7 with turbopack

[vicb]

The supposedly webpack e2e is actually also testing turbopack (it is the default when using next build without further option in Next 16).

This PR:

• makes it explicit that we use turbopack by using next build --turbopack (unchanged behavior)
• remove the "webpack" test that was actually testing turbopack
• cleanup unneeded files

LGTM, in the PR description you say webpack but I think you meant turbopack
