Steven 8dede2a4f5 chore(test): fix flaky tsconfig.json test (#53132) ... 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.		2023-07-24 14:33:55 -07:00
