Okay. So.

This PR works and relies on exercism/javascript-test-runner#852, but I do not know if that PR will work as it requires the tmp directory to be mounted with exec on as that's where pnpm installs the executables.

My plan is:

1. test the test runner against a non-upgraded exercise solution (so one that expects npm instead of pnpm)
2. merge the test runner
3. try this online

If that works, mark this as ready and we are good to go! If it doesn't work, I will revert the test runner and message Jeremy.

What a monster PR! Not even sure where to start with this...

Isn't it fun 📦.

Basically: eslint 9, pnpm instead of npm. Check that the instructions to install are clear and that you don't absolutely hate it.

Looks good from what I could see, appart from a few leftover comments.

@Cool-Katt where's the comments?

@SleeplessByte sorry, I accidentally forgot to post the actual review. Lol

@Cool-Katt apart from those three comments, anything else?

Everything else looks good to me

@Cool-Katt if you can approve we can merge!

@SleeplessByte Just to wrap my head around it, why are we having a separate babel and jest config for each exercise?

EDIT: Otherwise looks good, i think

Because neither likes to be defined in package.json and remember that students download the folders separately!
