Add React 17.x to peerDependencies

[maciejregula]

Hi,

When will React 17.x be added as peerDeependency?
When you have React 17.x and npm version 7 installed you need to install this pacakge with --force or --legacy-peer-deps flags, otherwise you get:

npm ERR! Found: [email protected]
npm ERR! node_modules/react
npm ERR!   react@"^17.0.1" from the root project
npm ERR!   peer react@">=16.8.0" from @emotion/[email protected]
npm ERR!   node_modules/@emotion/react
npm ERR!     peerOptional @emotion/react@"^11.0.0" from [email protected]
npm ERR!     node_modules/styled-breakpoints
npm ERR!       styled-breakpoints@"*" from the root project
npm ERR!
npm ERR! Could not resolve dependency:
npm ERR! peerOptional react@"^16.8.0" from [email protected]
npm ERR! node_modules/styled-breakpoints

Thanks!
