Bug: createBlockingRoot doesn't exist on react-dom@0.0.0-experimental-af1a4cbf7

[natew]

React version: 0.0.0-experimental-af1a4cbf7

Pretty simple, seems to just be missing entirely. Searching around I don't see any obvious commits or even tweets/notes on this, but the docs on the live site indicate it exists.

unstable_createBlockingRoot was removed in #20974.

Removing the mention from the docs entirely might be confusing. A note about it under https://reactjs.org/docs/concurrent-mode-reference.html#createblockingroot should work. Though I don't know if the core team intends to write something about the reasoing or if "it was removed" is sufficient. Maybe @rickhanlonii has an opinion about it.

createBlockingRoot was an unstable API that we determined was not necessary for a stable release. The docs in question do mention right at the top that all APIs are experimental and unstable.

We will have stable docs for the final/stable API by the time we release it to the stable NPM channel though 😄
