Vendor react@experimental (#48697)

Part of #47759 (which had been reverted twice so here we only land a part of the change), relates to NEXT-926. Thanks to #48506 we can soon switch between these two channels during runtime.

Also fixes a problem of `renderKind` (only revealed after upgrading React), it should be also based on the `match` kind.
