This PR migrates the codebase from CRA and Jest to Vite and Vitest.

Changes:

• Update public folder in firebase.json to dist from build
• Change REACT_APP env variables to VITE_APP
• Move index.html to root as it is required by Vite
• Update packages like use-debounce, json2csv as their newer versions have proper support for ESM
• Remove esModuleInterop from tsconfig to keep our app as close as possible to create-vite-app template
• Instead of Webpack's raw-loader use Vite specific loader argument
• Use import.meta.env instead of process.env as recommended by Vite
• Migrated to Vitest from Jest. Vitest has better ecosystem integration with Vite and its API is also similar to Jest.
• Add colord because it was missing from package.json.

Checking out to this PR won't work. To test locally you'll have to checkout to rowyio/form-builder#10 and use yarn link. I have made some changes to that package. Reason for the change is explained in rowyio/form-builder#10.

I have tested the changes locally after linking to @rowy/form-builder. yarn build, yarn start work as expected. yarn test fails with a firebase auth/network-request-failed. ( Help needed )

For this PR, I have used @vitejs/plugin-react and not @vitejs/plugin-react-swc because jotai doesn't support fully support swc. I did try swc at first but it didn't work.
