Incomplete `vitest` config configuration for rule `vitest/expect-expect` fails if a tests has only type assertions (`expectTypeOf`)

User story

As a testing engineer I want to be able to write test cases that only include type tests.

Example test:

import { assertType, expectTypeOf, describe, it } from 'vitest'
import { mount } from './types.s'

describe('', () => {

  it('my types work properly', () => {. // 👈 this is failing because of a violation of `vitest/expect-expect`
    expectTypeOf(mount).toBeFunction()
    expectTypeOf(mount).parameter(0).toMatchTypeOf<{ name: string }>()
  
    // @ts-expect-error name is a string
    assertType(mount({ name: 42 }))
  })
  
})

This violates the vitest/expect-expect rule in the current configuration.

Acceptance criteria

• A test case containing only expectTypeOf should pass the vitest/expect-expect rule

Minimal reproduction of current behaviour

import { assertType, expectTypeOf, describe, it } from 'vitest'
import { mount } from './types.s'

describe('', () => {

  // eslint-disable-next-line vitest/expect-expect  // 👈 needed to pass lint target
  it('my types work properly', () => {
    expectTypeOf(mount).toBeFunction()
    expectTypeOf(mount).parameter(0).toMatchTypeOf<{ name: string }>()
  
    // @ts-expect-error name is a string
    assertType(mount({ name: 42 })) 
  })
  
})

Desired behaviour showcase

import { assertType, expectTypeOf, describe, it } from 'vitest'
import { mount } from './types.s'

describe('', () => {

  it('my types work properly', () => { // 👈 lint target passed without disabling rules
    expectTypeOf(mount).toBeFunction()
    expectTypeOf(mount).parameter(0).toMatchTypeOf<{ name: string }>()
  
    // @ts-expect-error name is a string
    assertType(mount({ name: 42 }))
  })
  
})
