Following up on https://github.com/reactjs/reactjs.org/pull/4486#discussion_r834319756 (/cc @acdlite )

React version: 18.0.0-rc.3-next-1159ff619-20220324

## Steps To Reproduce

1. schedule an update (e.g. `setState`) from within `useInsertionEffect` 


Link to code example: https://codesandbox.io/s/naughty-bogdan-boghf6?file=/src/index.js


## The current behavior

Update is applied and no warning is issued.

## The expected behavior

According to https://github.com/reactjs/reactjs.org/pull/4486/files#diff-a1c8ec10dc40c86b4bbd55ad3f0126835bd45e9aa9e56c846a2e28ad6dd6acffR602 `useInsertionEffect` cannot schedule updates. But `setState` seems to "work". Maybe this is just incidental because it's the first render?

I got the impression that this should definitely cause a warning (not implemented) but I wonder if we also should consistently drop updates from `useInsertionEffect`?
if (
      root.tag !== LegacyRoot &&
      isConcurrentActEnvironment() &&
      ReactCurrentActQueue.current === null

      console.error(
        'A suspended resource finished loading inside a test, but the event ' +
          'was not wrapped in act(...).\n\n' +
          'When testing, code that resolves suspended data should be wrapped ' +

          'act(() => {\n' +

          '});\n' +
