chore(tests): replaced jest with node:test

[floridemai]

Closes #243

Updated all test files to work with node:test runner. Everything went smooth with only two notes: certain expected objects needed and addiional $id: undefined property and a test where the error type was invalid.

@mcollina build is failing on Node 16, I suspect something incompatible with c8 or even node:test. Are we supposed to still support Node 16 with this library?

Please target next and modify this line to test only on 18, 20, 22:

fluent-json-schema/.github/workflows/ci.yml

Line 24 in 9e91b2c

Thank you for this @floridemai 🙌

We can just drop node.js v16

We can just drop node.js v16

I think to keep things organized we should keep CI changes in next too, we'll start merging next branches this month or in July anyway for Fastify v5

Thanks a lot for the PR!
