This PR adds documentation about the microtask scheduling behavior of
createRoot().render(), as requested in #7317 and confirmed by the React team in facebook/react#32811.The documentation clarifies that while rendering is synchronous once it starts, the
render()call itself is scheduled in a microtask, similar to howsetStateworks. This can be important when integrating with code that depends on precise effect timing (remix-run/react-router#12459)Fixes #7317
Closes facebook/react#32811
