Remove errorHydratingContainer (#28664)

I originally added this in #21021 but I didn't mention why and I don't
quite remember why. Maybe because there were no other message? However
at the time the recoverable errors mechanism didn't exist.

Today I believe all cases where this happens will trigger another
recoverable error. Namely these two:

https://github.com/facebook/react/blob/9f33f699e4f832971dc0f2047129f832655a3b6d/packages/react-reconciler/src/ReactFiberBeginWork.js#L1442-L1446

https://github.com/facebook/react/blob/9f33f699e4f832971dc0f2047129f832655a3b6d/packages/react-reconciler/src/ReactFiberBeginWork.js#L2962-L2965

Therefore this is just an extra unnecessary log.
