chore(tests): apply prettier formatting to concurrent-render.test.tsx

Fixes the sole remaining check flagged in @nrps9909's re-review of
head 5fe5e27: `npx prettier --check tests/concurrent-render.test.tsx`
was reporting the file needed formatting. Ran `prettier --write`
locally; only whitespace changed and `npx prettier --check` is now
clean. Full suite still 20 / 137 (+1 pre-existing skip).
