Fix node-20, reenable node-latest in CI

[ssalbdivad]

Currently I'm unable to find a reasonable solution for using ts-node (or others like tsx)/ts-morph reliably with Node 20.

I believe it was related to a breaking change with how subprocesses are spawned, but ts-morph constantly hangs when running attest, and when trying to use vscode's builtin debugger, more and more processes are continuously spawned, e.g. :

Source maps also appear to be broken on Node 20.

Would love if someone could take a look at this but unfortunately I've spent too long on it and the current plan is to wait until Node 20 stabilizes a bit as it's basically just broken everything I've tried it with.

Once these issues are resolved, CI can be reenabled here:
