chore: update pnpm to the latest version (#5099)

## 📄 Description

This PR updates the project’s package manager from [email protected] to
[email protected].

To address issues caused by the upgrade:

✅ Added eslint-plugin-react to fix ESLint config resolution in
documentation

✅ Added cypress as a dev dependency to ensure the binary installs
correctly. The problem was introduced after upgrading to pnpm@10, which
no longer runs dependency lifecycle scripts (like cypress install) by
default. cypress-io/cypress#31111
