RequestedUpdateValidator should subscribe to StatusCheckEvent

I am not why this error is happening

I don't think we should just blithely paper over this problem by running RequestedUpdateValidator during status check. We need to know exactly why this is happening before we commit to a particular solution.

@phenaproxima Great point, I'll investigate that to allow this issue to continue!

I tried to reproduce it locally but wasn’t able to do it. I tried to update drupal/core from 10.0.0 to 10.0.9 and it successfully updated without any errors.

re #5 I found this is test where I was upgrading and then manually downgrading many times. I couldn't reproduce it again.

So I am not sure how to make this happen.

But regardless I think we should fix this just incase it happens to someone. We can know at the point where they are on the UpdateReady form if the will get this error so we should remove the "continue" button. Listening to StatusCheck will do that.

I think this looks good if tests pass after the 3.0.x merge.

Assigning to @phenaproxima to see if he agrees

@phenaproxima I create follow-up 🐛 Bug where drupal/core-vendor-hardening does not get updated, STR unknown Active and assigned to you because you have seen this happen more that the 1 time
