What steps will reproduce the bug?

require('module').builtinModules

How often does it reproduce? Is there a required condition?

No response

What is the expected behavior?

Everything that's requireable that ships with node is listed (or, the listed items are requireable with node: added).

What do you see instead?

node:test is not listed.

Additional information

There needs to be a way to programmatically discover all builtin modules. require('module').builtinModules is supposed to be it.

This broke assumptions in my tests for https://npmjs.com/is-core-module - specifically, CIGTM should have failed prior to node 18 going out, because node:test wasn't part of is-core-module, but by making it effectively "secret", my tests didn't know about it.
