Breaking change introduced in 2.10.0

[hudochenkov]

Version 2.10.0 uses useInsertionEffect, which is not available in React 17. It breaks the build:

ERROR in ./node_modules/wouter/react-deps.js 46:2-27

export 'useInsertionEffect' (imported as 'useBuiltinInsertionEffect') was not found in 'react' (possible exports: Children, Component, Fragment, Profiler, PureComponent, StrictMode, Suspense, __SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED, cloneElement, createContext, createElement, createFactory, createRef, forwardRef, isValidElement, lazy, memo, useCallback, useContext, useDebugValue, useEffect, useImperativeHandle, useLayoutEffect, useMemo, useReducer, useRef, useState, version)

In the error webpack can't find export, which is correct, since React 17 doesn't have this hook.

You can go back to v2.9.x first. maybe should add some description about it in readme

I believe this can be fixed simply by changing

import {
  useEffect,
  useLayoutEffect,
  useRef,
  useInsertionEffect as useBuiltinInsertionEffect,
} from "react";

to:

import * as React from "react";
const {useEffect, useLayoutEffect, useRef, useInsertionEffect: useBuiltinInsertionEffect} = React;

The intention was for useInsertionEffect to be undefined on React 17, not throw an error. (And if so, use useLayoutEffect instead).
