chore: migrate to pnpm for package management and update CI configuration

- Replaced npm with pnpm in the CI configuration and Dockerfile for improved dependency management.
- Updated package.json to specify pnpm as the package manager.
- Modified installation instructions in README.md to reflect the use of pnpm.
- Enhanced the build process in the Dockerfile to utilize pnpm for installing dependencies and building the application.
