[Bug]: config:init should create ESM version of jest.config.js when type = module

[pointlesscore]

Version

29.0.5

Steps to reproduce

1. Create an npm project that has "type": "module" in its package.json
2. Install jest, typescript, and ts-jest
3. Run config:init script to generate jest.config.js
4. Run jest

yarn create vite --template vanilla-ts esm-config-ts-jest
cd esm-config-ts-jest
yarn add jest @types/jest ts-jest
yarn ts-jest config:init
yarn jest

Expected behavior

Jest reads the config file and runs normally if tests found.

Actual behavior

Jest can't read the config file because:
ReferenceError: module is not defined in ES module scope

Debug log

n/a

Additional context

It's not the biggest bug, and can easily be fixed manually, by changing the generated jest.config.js to ESM. But it would be nice if it just worked out of the box.
It should be a simple fix in the cli/config/init.ts script, I can make a PR if it's okay.

It would have been nice to show how, for those of us who have this bug and are looking to fix it.

You can either change the config's extension to .cjs,

or change

module.exports = {
// config
}

to ESM (any requires should also be changed to import statements)

export default {
// same config
}
