This test was [sometimes failing](
https://github.com/vercel/next.js/actions/runs/5649220907/job/15303327768?pr=53130#step:27:230)
because the `tsconfig.json` is [written as an empty
object](a26bac9604/packages/next/src/lib/typescript/writeConfigurationDefaults.ts (L123-L125)
).
This PR makes sure the test waits until the tsconfig.json file is
written with the complete contents.
