A rich assert library for the node test runner

This is a drop-in replacement for the node:asert/strict library.
Why? There are a few reasons:

* The node assert library is a little bit confusing.
There are both non-strict and strict variants of the assertions.
The former is a legacy design mistake and the later should be preferred.
The rich-assert library provides only strict assertions.
* The node assert library is a little bit lacking. It provides a bare minimum
set of assertions and forces us to write verbose tests.
The rich-assert library provides some new useful assertions for writing
shorter tests. One of those new assertions is like for partial comparison
of objects. It only checks a subset of object properties and provides
a detailed explanation of where the objects differ, at which array index
or object key.

rich-assert is really a tiny wrapper around node:assert/strict. It simply
re-export the strict asserts and adds a few more helpful functions.

Usage

``javascript
import { test } from "node:test";
import { deepEqual, includes, like, isTrue, isNull, isEmpty } from "rich-assert";

test("test", () => {
// Every assertion is strict.
deepEqual({ foo: 1, bar: 2 }, { foo: 1, bar: 2 });
includes([1], 1);
like({ foo: 1, bar: 2 }, { foo: 1 });
isTrue(true);
isNull(null);
isEmpty([]);
});
