Switch to pnpm

[smoliji]

My first hands-on migration from npm to pnpm. I've...

• used https://github.com/pnpm/action-setup to make pnpm available in Actions, left without version to automatically pick version from packageManager
• installed pnpm with curl -fsSL https://get.pnpm.io/install.sh | sh -
• replaced npm commands with pnpm commands
• removed package-lock.json
• set packageManager and devEngines to package.json (npm ci now fails ✅ )

Anything that could've missed or misplaced?

Thanks for going with some try on this, would be nice to agree together on what is the best value here with the team. But we can change later for sure as well. 👍

Also consider using

• trust policy
• blockExoticSubdeps
