yarn test (node --run test) fails in Node.js 22.12 due to requiring top-level await module

[tats-u]

Environments:

• Prettier Version: b40509c (main)
• Running Prettier via: Node.js
• Runtime: Node.js 22.12.0
• Operating System: Windows
• Prettier plugins (if any): N/A

Steps to reproduce:

node --version
git clone https://github.com/prettier/prettier.git
cd prettier
yarn
yarn test
node --run test

Expected behavior:

(Test succeeds twice)

Actual behavior:

v22.12.0

Error [ERR_REQUIRE_ASYNC_MODULE]: require() cannot be used on an ESM graph with top-level await. Use import() instead. To see where the top-level await comes from, use --experimental-print-required-tla.

yarn why temp-dir

   └─ temp-dir@npm:3.0.0 (via npm:^3.0.0)

We have to await import("tempy") and propagate asyncness to callers.
It finally reaches to jest.config.js, but Jest seems to decline to read it.

This makes the test work again, but I don't want Prettier to set it because it's just a makeshift:

↑ These look like culprits.

I think we need to make all test scripts modules.

22.12 introduced require(esm) without flag: nodejs/node#55217, but it looks like incompatible with the current test code of Prettier.
