refactor: migrate to node test runner

[barelyhuman]

Refactors the following to use node test runner instead of Tap

• Examples
• Slide Dec

Note

The timeout issue still exists, as it's a problem with node v20 itself and not tap / node test runner.

Workaround for the infinite loop and getting stuck is to use Node 21, which doesn't sit well with the lts/* rule we have.

References

• Infinite loop at shutdown  nodejs/node#47748
• sometimes dead loop, maybe should update foreground-child version bcoe/c8#495

closes: #1128

The switch to node test runner looks fine, just a couple of small comments.

Regarding the bug with node 20, is this a known issue? Is there an existing bug issue to track it?

haven't found one, the one in references is one of the few duplicates about the same error. The workaround of using a newer node version seems to be working based on the following action

https://github.com/nearform/the-fastify-workshop/actions/runs/7736673623/job/21094398580

The original action in the repository seems to go on and on and so the workaround works but I do not have any idea about the root cause

LGTM, good job
