Adjust react version in peerDependencies

[pgrodrigues]

This PR addresses the version issue when using react-swipeable-views in a project with "react": "^17.0.1" as dependency and running npm install:

npm ERR! Found: react@17.0.1
npm ERR! node_modules/react
npm ERR!   react@"^17.0.1" from the root project
npm ERR!
npm ERR! Could not resolve dependency:
npm ERR! peer react@"^15.3.0 || ^16.0.0" from react-swipeable-views@0.14.0-alpha.0
npm ERR! node_modules/react-swipeable-views
npm ERR!   react-swipeable-views@"^0.14.0-alpha.0" from the root project
npm ERR!
npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force, or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

Reproducible with Node.js v14.16.0 and npm v7.6.1.
