docs(spec): leave driver/turso.test.ts to the open PR that now holds it (stage 3)

The #20437 PR opened after this stage's claim and edits
packages/spec/src/data/driver/turso.test.ts, so that file joins the stage's
exclusions beside driver/turso.zod.ts. Its two comment sites return to the
base bytes (blob 7fe99eb) and wait for a later stage.
