test_runner: todo/skip/expectFailure are truthy per docs, but implementation is otherwise

Version

v25.6.1

Subsystem

node:test

What steps will reproduce the bug?

Add the todo, skip or testFailure option to a test, setting it to an empty string. The result will be the same as if you set it to true or a non-empty string.

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

Unsure whether the bug is in the code or in the API docs.

The code clearly does not treat these options as truthy:
https://github.com/nodejs/node/blob/2de34822cc9a19621a663e3f22b00b9a01697635/lib/internal/test_runner/test.js#L639-L641

But the docs specifically state they should be:

先查看 lib/internal/test_runner/test.js 约第 639-641 行，以及 doc/api/test.md 约第 1691-1696 行的选项说明。审阅链接的讨论，以确定空字符串是否应被视为已启用，或者文档是否有误。完成标准是文档与实现一致，并且覆盖空值、true 和非空值。
