chore: optimize CI pnpm setup

[chenjiahan]

Summary

This PR aligns the GitHub Actions pnpm setup with the current Rsbuild workflow pattern from web-infra-dev/rsbuild#7856.

• Replace corepack/manual pnpm install steps with pnpm/action-setup@0e279bb959325dab635dd2c09392533439d90093 and run_install: true.
• Explicitly disable actions/setup-node package manager caching with package-manager-cache: false.
• Keep browser installation commands as separate post-install steps where needed.

📝 Walkthrough

Walkthrough

Both the release and test GitHub Actions workflows are updated to standardize their Node.js and Pnpm package manager setup. The workflows now use actions/setup-node@v6 with package-manager-cache: false and replace Corepack-based Pnpm installation with pnpm/action-setup (configured with run_install: true). This removes separate Corepack and pnpm install steps from both workflows.
