* Move useSyncExternalStore shim to a nested entrypoint Also renames `useSyncExternalStoreExtra` to `useSyncExternalStoreWithSelector`. - 'use-sync-external-store/shim' -> A shim for `useSyncExternalStore` that works in React 16 and 17 (any release that supports hooks). The module will first check if the built-in React API exists, before falling back to the shim. - 'use-sync-external-store/with-selector' -> An extended version of `useSyncExternalStore` that also supports `selector` and `isEqual` options. It does _not_ shim `use-sync-external-store`; it composes the built-in React API. **Use this if you only support 18+.** - 'use-sync-external-store/shim/with-selector' -> Same API, but it composes `use-sync-external-store/shim` instead. **Use this for compatibility with 16 and 17.** - 'use-sync-external-store' -> Re-exports React's built-in API. Not meant to be used. It will warn and direct users to either the shim or the built-in API. * Upgrade useSyncExternalStore to alpha channel
