Add Dockerfile for Node.js environment setup

[hoangsonww]

This pull request adds a new .github/Dockerfile to set up a development environment using the latest Node.js image, along with several useful utilities and shell customizations. The Dockerfile is designed to streamline onboarding and ensure consistency across development setups.

Environment setup:

• Added a new .github/Dockerfile that uses the latest Node.js image and installs common development utilities (e.g., git, curl, build-essential, postgresql-client, zsh).
• Configured the container to use the America/New_York timezone and set up non-interactive apt installs for smoother automation.
• Configured the working directory to /workspace and copies the project files into the container.
• Exposed port 3000 for application access.

Shell customization:

• Installs and configures oh-my-zsh with the kennethreitz theme and updates the PATH in .zshrc for improved developer experience.
