aws-cdk: Warnings on cdk init

[sholtomaud]

Describe the bug

Applying project template app for typescript

Welcome to your CDK TypeScript project

This is a blank project for CDK development with TypeScript.

The cdk.json file tells the CDK Toolkit how to execute your app.

Useful commands

• npm run build compile typescript to js
• npm run watch watch for changes and compile
• npm run test perform the jest unit tests
• npx cdk deploy deploy this stack to your default AWS account/region
• npx cdk diff compare deployed stack with current state
• npx cdk synth emits the synthesized CloudFormation template

Executing npm install...
npm warn deprecated [email protected]: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm warn deprecated [email protected]: Glob versions prior to v9 are no longer supported
✅ All done!

I am considering working on this issue. Therefore, I would like to discuss a few things.

Premise

When I checked the contents of package.lock.json, the issue mentioned in this issue seems to be caused by jest (and related libraries).
(In fact, when I personally removed jest and ran npm install, this error did not occur.)

Therefore, I am considering submitting a PR to modify it to use vitest instead of jest.

Things I Want to Discuss

I would like to discuss the following two points.

1. About the test package

Is it permissible to adopt vitest instead of jest?

2. Testing the initial template

If you update the TypeScript init-template, the TypeScript init tests may fail.
(In fact, the PR to update tsconfig.json below has been reverted.)

#31953

So, I would like to verify the correct operation in MR. Is the following method of verifying the operation correct?

1. Add a test to the following file

• packages/aws-cdk/test/init.test.ts

2. Run the following integ test

• packages/@aws-cdk-testing/cli-integ/tests/init-typescript-app/init-typescript-app.integtest.ts
