Clear and concise description of the problem

In Vitest tests you can do this:

expect('b').toBeOneOf(['a','b','c','d']);

but not this:

const values = new Set(['a','b','c','d']);
expect('b').toBeOneOf(values);

You get this error: TypeError: You must provide an array to expect(received).toBeOneOf(expected), not 'object'.

Suggested solution

I think toBeOneOf is a classic Set operation and I think Vitest should support it. I think the implementation should be very straightforward and I am happy to provide a PR for it.

Alternative

There are simple workarounds of course, as you can just do this:

expect('b').toBeOneOf([...values]);

(I had to do this at work recently)
But I don't see a reason why Vitest should not just support this out of the box.
