Migrate to pnpm for faster everything

[aryanprince]

Why

Faster dev, faster installs, faster CI, fast everything.

So when we change our package manager, then everyone would have to do pnpm dev instead of npm run dev to run our project locally.

Basically pnpm is a faster package manager than npm, but they both use the npmjs.com package ecosystem, it's just that pnpm installs/works faster

How

1. Delete our node_modules folder
2. Delete package-lock.json
3. Run pnpm import
4. Run pnpm install

Tips

Look into https://pnpm.io/cli/import or other blogs explaining how they migrated from npm to pnpm
