What steps will reproduce the bug?

const test = require('node:test');

test('Parent', t => {
	t.test.only('Child only', () => {});
	t.test.skip('Child skip', () => {});
	t.test.todo('Child todo', () => {});
});

Run with node --test <file> (same result without the --test flag)

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

Consistently

What is the expected behavior? Why is that the expected behavior?

All functions work as described here: https://nodejs.org/docs/latest-v20.x/api/test.html#subtests

This method behaves identically to the top level test() function. The following example demonstrates the creation of a top level test with two subtests.

What do you see instead?

TypeError [Error]: t.test.todo is not a function

TypeError [Error]: t.test.skip is not a function

TypeError [Error]: t.test.only is not a function

Additional information

These functions work for top-level test, they don't work for nested tests.
Maybe it doesn't make sense to expose those functions for subtests (use just describe - maybe it's enough), but in that case the documentation is misleading

node:test のサブテスト API エントリーポイントから開始し、提供されたネストされたテストを node --test またはフラグなしで再現します。t.test.only、t.test.skip、t.test.todo のドキュメントに記載された動作を、観測された TypeErrors と比較します。ネストされた API の動作とドキュメントが意図された動作について一致すれば完了です。
