chore: Update package.json and GitHub Actions workflow for pnpm integration

- Changed the "prepare" script in package.json to use pnpm instead of npm.
- Added npm configuration step in the GitHub Actions workflow to handle authentication for publishing.
- Simplified the publish step by removing redundant npmrc configuration commands.
