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`?
const renderWasConcurrent = !includesBlockingLane(root, lanes);
      const finishedWork: Fiber = (root.current.alternate: any);
      if (
        renderWasConcurrent &&
        !isRenderConsistentWithExternalStores(finishedWork)
      ) {
         
         
        exitStatus = renderRootSync(root, lanes);
         
        if (exitStatus === RootErrored) {
          const errorRetryLanes = getLanesToRetrySynchronouslyOnError(root);
          if (errorRetryLanes !== NoLanes) {
            lanes = errorRetryLanes;
            exitStatus = recoverFromConcurrentError(root, errorRetryLanes);
             
             
          }
        }
        if (exitStatus === RootFatalErrored) {
          const fatalError = workInProgressRootFatalError;
          prepareFreshStack(root, NoLanes);
          markRootSuspended(root, lanes);
          ensureRootIsScheduled(root, now());
          throw fatalError;
        }
      }
