Should vi.setConfig({ sequence: { shuffle: false } }) be in RuntimeConfig TypeScript type?

[andykenward]

Describe the bug

When setting sequence.shuffle via the cli or vitest.config.ts. Should you be able to override this in a test file via

vi.setConfig({
  sequence: {
    shuffle: false
  }
});

The above does indeed overrides the cli or vitest.config.ts. But the TypeScript types for RuntimeConfig does not allow this. There is a TypeScript error of

Object literal may only specify known properties, and 'shuffle' does not exist in type '{ hooks?: SequenceHooks | undefined; }'.ts(2353)

I see in v3 of Vitest there will be feat(runner)!: support describe(..., { shuffle: boolean }) and inherit from parent suite

 describe('not random', { shuffle: false }, () => {
    test('in order 5.1', async () => { /* ... */ })
    test('in order 5.2', async () => { /* ... */ })
  })

Should v3 TypeScript types for RuntimeConfig support shuffle as well?

I think we can expose it if it works, but I'm a bit unsure if it actually works. I vaguely remember that I had to set file.shuffle early before evaluating a test file, so vi.setConfig cannot overwrite 🤔
(Overwriting undefined -> true/false might work, but false -> true and true -> false might not?)

vitest/packages/runner/src/collect.ts

Lines 34 to 35 in f9a6284

	const file = createFileTask(filepath, config.root, config.name, runner.pool)
	file.shuffle = config.sequence.shuffle

Can you provide your working example? Also feel free to try a PR with adding a type with test cases.
