enhancement: 'to have items satisfying'

[boneskull]

It'd be handy to be able to express "every item in the set should satisfy assertion" (like the core "array" assertion), which I don't think is currently possible.

e.g.:

const set = new Set(['foo', 'bar', 'baz']);
expect(set, 'to have items satisfying', expect.it('to have length', 3));

You're in luck! <Set> to have items satisfying <assertion> has been implemented since the initial commit :)

It has been undocumented until 18 days ago (#37), though, and it looks like we forgot to update the documentation site after it landed. But here it is: https://unexpected.js.org/unexpected-set/assertions/Set/to-have-items-satisfying/ 🤗
