False positive: Expect has unknown modifier (vitest/valid-expect)

[alexkiro]

It seems this is wrongly marked as incorect:

  expect("foo bar").to.include("foo");

The rule is incorrectly triggered, as this is in fact valid :

  6:3   error  Expect has unknown modifier                 vitest/valid-expect

I have the same issue for expect().to.have.property()

Tests pass without any issues. However, this plugin doesnt like it
