[no-standalone-expect] False positive inside it.fails

[KoenBrouwer]

Summary
vitest/no-standalone-expect seems to wrongly warn about an expect that is not standalone.

Steps to reproduce
Use Vitest with vitest/no-standalone-expect enabled in ESLint, run the following test:

// .eslintrc

{
    "plugins": [
        "vitest",
    ],
    "rules": {
        "vitest/no-standalone-expect": [
            "error"
        ],
    },
}

// test.ts

it.fails("should work", () => {
    expect(true).toBe(false);
});

What you expected would happen
ESLint shouldn't error on the expect, as it clearly is inside a test/it block.

What actually happens
ESLint warns/errors (depending on your setting):

it.fails("should work", () => {
    expect(true).toBe(false);
     ^^^ ESLint: Expect must be called inside a test block(vitest/no-standalone-expect)
});

Maybe related to #182?
