Update interactive_setup.py to improve virtual environment creation…

… and installation process

* **Virtual Environment:**
  - Replace `subprocess.run` with `venv.create` for creating virtual environments
  - Return the activation script path after creating the virtual environment

* **Dependency Installation:**
  - Use `sys.executable` to run `pip` for installing dependencies

* **Global Installation:**
  - Rename `global_install` to `global_installation`
  - Use `sys.executable` to run `pip` for global installation

* **Docker Setup:**
  - Use consistent single quotes for `subprocess.run` commands
