Should `vi.setConfig({ sequence: { concurrent: true } })` work?

[hi-ogawa]

Describe the bug

Docs now mentions it's not supported https://vitest.dev/api/vi.html#vi-setconfig But it's available as typing of vi.setConfig. https://github.com/vitest-dev/vitest/blob/2a50464d58e98f58fed513971a570a952081bfef/docs/api/vi.md?plain=1#L977-L980

But it might be a regression and possible to make it work again https://github.com/vitest-dev/vitest/pull/6653#issuecomment-2403730192

If not, we should update RuntimeConfig to hide it from typing.

Conceptually, I don't see why it wouldn't work:

vi.setConfig({ sequence: { concurrent: true } })
describe('suite1') // concurrent
describe('suite2') // concurrent
describe('suite3', { concurrent: false }) // sequential

The question is here, I guess:

describe('suite1', () => {
  vi.setConfig({ sequence: { concurrent: true } })
  describe('suite2') // should it inherit parent suite options or follow global config?
})
