VSCode Test Explorer unable to run tests

[drmacm]

Summary

After cloning the repo, VSCode's Test Explorer is unable to run the tests in the app.
The tests work when running npm run test:unit in terminal.

Fixed by running npm install jest-environment-jsdom --save-dev.

I can submit a PR with extra dependency if you agree with the approach.

Hello,

This issue occurs because Jest v28 stopped bundling the extra jest-environment-jsdom dependency. This is required for LWC, and has been pre-packaged by sfdx-lwc-jest.
I'll update sfdx-lwc-jest to get it fixed.

Thanks for your contribution!
