create-react-app for Browser Extensions

Hey 👋 thanks for that! Yesterday I tried to build a Chrome extension for Zencal.io I did POC (proof of concept) but I feel I need more. This repo will be very useful for me! I left a star 🎉

I've tried lots of extension boilerplates, either they work only in chrome or manifest v3, hard to integrate react and stuff for building large extensions or mostly don't work. This one just works out of the box, just "Use Template" to create your extension, and follow the start commands -- done!
