Update peerDependencies to include React 18

[nil4]

React 18 is now available: https://reactjs.org/blog/2022/03/29/react-v18.html

Trying to use react 18 together with react-select v5.2.2 (latest version) currently leads to a dependency conflict:

> npm install
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! While resolving: app@0.0.0
npm ERR! Found: react@18.0.0
npm ERR! node_modules/react
npm ERR!   dev react@"^18.0.0" from the root project

npm ERR! Could not resolve dependency:

npm ERR! node_modules/react-select
npm ERR!   dev react-select@"5.2.2" from the root project

This seem to be related to the peerDependencies defined here:

react-select/packages/react-select/package.json

Lines 29 to 31 in 2d3d6af

	"peerDependencies": {
	"react": "^16.8.0 || ^17.0.0",
	"react-dom": "^16.8.0 || ^17.0.0"

Would it be possible to publish a new version which allows react 18 too?
