fix: fix missing path-browserify dependency. #198

Module not found: Error: Can't resolve 'path' in '/home/runner/work/react-color/react-color/node_modules/@babel/core/lib/transformation'
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
